Time: After "Northwest Mansion Mystery"

Place: Trembley Home

Preston entered the visitor's room, where Northby was strapped down to a stretcher. His wrists and ankles were held down by leather straps as well. He quickly turned off the surveillance camera in the corner before turning to his son.

"Do you remember the conditions for lifting the Lumberjack's Curse?" Preston asked.

"A Northwest has to open the gates to the townsfolk on the 150th anniversary of the first Northwest Fest," Northby said. "You're still alive, so I assume you exorcised the ghost…"

"Who qualifies?" Preston asked.

"You, of course, and myself and Pacifica, but I don't see…" Northby stopped. "Wait. You would never open the gates, so…"

"Yes, your sister opened the gates and let that riffraff roam free!" Preston said. "And it's all your fault!"

"How is it my fault?" Northby asked. He'd facepalm, were the leather restraints not holding his wrists down.

"You were a bad influence on her!" Preston roared.

Northby frowned. "How could I have been a bad influence?! I haven't seen her in three years!"

"You planned this," Preston snapped. "Three years ago. You've been plotting against the Northwest Fest from the start! You knew I'd get rid of you because you would be willing to open the gates, so somehow you tricked your sister into opening the gates."

"How do you know she didn't choose to open the gates of her own will?" Northby retorted. "Maybe she's finally finding the courage to stand up to you."

"She would never hurt me like that," Preston said. "She loves me."

"No, you intimidate her into obeying your every whim. It's not love. It's coercion," Northby said.

"And why can't you follow her example?" Preston asked. "I know clay pots need to be fired as well as shaped to burn out any impurities, but you've resisted any attempt to make you just like me."

"I don't want to be like you," Northby said quietly.

"You just don't comprehend the glorious privilege that comes with being born a Northwest," Preston said. "Why do you think I sent you here?"

"To get me to accept your twisted way of thinking," Northby answered. "To gaslight me, isolate me, and break down my resistance."

"I wish it was working," Preston said, opening his briefcase. He pulled back a tab on the briefcase's backing, revealing a hidden pocket. He took out a lighter and a small pack of sewing needles. "I see I need some more fire to burn out your impurities."

Northby thrashed against the bonds. "No, please. I haven't done anything. Don't do this!"

Preston flicked open the lighter and passed one of the needles into the flame until the tip was red hot. He then guided the hot needle under the fingernail on Northby's right index finger.

Twenty minutes later, the door unlocked. Preston stepped out, whistling gaily. "I'm done with my visit," Preston said to the asylum director.

The director entered the room. "Are you all right?"

"Please take me back to my room," Northby said quietly.

"Do you want to talk about the visit?" The director asked.

"No, I want to go back to my room!" Northby screamed. "Was I not clear?!"

The director sighed and unbuckled the leather straps, then led the sullen Northby to his room. He curled up on his bed and began to cry.

The director left, shutting the door behind him.

Ten minutes later, the door swung open, revealing one of the Trembley Home's other juvenile patients, Poppy Cox. She wore a brightly colored flowered dress with short sleeves. Healed scars were visible on both wrists, indicating at least one previous suicide attempt.

Northby turned and glared at her. "I hope you realize it is unforgiveable to enter someone's room without their permission."

"Look, Northby," Poppy answered. "Every time your father visits, you hide in your room for three days or more and don't talk to anyone. You don't even eat. Doesn't take a shrink to realize something's very wrong. And it's not good to hold it in."

Northby turned away from her, hugging his pillow to himself. "I do not wish to discuss it."

"Yeah, that's your standard answer," Poppy said, grimacing. "But every time your father comes, you're back to Square One in your treatment."

"I don't need treatment," Northby retorted. "My father threw me in here just to dominate me."

"And why don't you show any anger about that? I hate living here, and I actually belong here." Her tone on the last part was overly cheerful.

"The last time I showed my anger, I was strapped down and got a shot of Ativan to my thigh for my trouble," Northby said through gritted teeth. "It's no use resisting, so..."

Time: Chapter 4, just after Mabel hung up on the phone call with Stan and Ford

Place: Khura'in Orchard

"What?" Stan asked as Ford put away the cell phone. "I only promised their parents I wouldn't swear in front of them over the summer. Summer's over."

Ford sighed. "You're missing the point. Why did she need holy water? Maybe we should go back to Gravity Falls…"

"We could, but whatever's been eating all the food is going to keep doing it," Stan said. "The fields are bare. We'd be leaving a whole country to starve. As much as I'd like to run back and protect the kids, I have to trust Soos and Wendy."

"You're right," Ford said. "We can't let innocent people suffer any more than they have."

Stan stood up from where he had been sitting against one of the trees. "I'm going to check out the perimeter again." Suddenly, he let out a yell and ducked as a blade flew past his head and embedded itself in the trunk of a nearby tree.

"This thing just threw a knife at my head!" Stan complained, jumping on a dark, hunched-over figure and trying to hold it down. He was not quite successful, the figure trying to buck him off like a bull at a rodeo.

Ford glanced back at the bladed weapon sticking out of the tree. "It's a kukri, if you want to get technical."

"I don't want to get technical!" Stan yelled. "This thing is throwing pointy things at me, and I don't like it!"

Ford took out a demon-dispelling charm and ran toward Stan and the mysterious being. "I'm coming!"

Time: During Chapter 5

Place: Gideon's office

"So what would you say if I could testify against Dipper Pines? Swear that he was the one who murdered Toby while I distracted Mabel at the Mystery Shack?"

"Using a clone to establish an alibi," Gideon said. "Ha. Dipper Pines thought he could get away with such a cheap trick. You can't fool me, Pines! I'm the one who fools! But to answer your question, Tricky…"

"Tracey," Tracey corrected.

"Whatever," Gideon replied dismissively. "I'd say, what's in it for you? He's your creator. Why do you want him imprisoned and executed?"

"I hate him," Tracey answered. "He went back to Piedmont. Abandoned me and my brother. No, forgot us. After he casually murdered our clone brethren. I trusted him, believed in him…"

"So you want him executed, disgraced, and then swoop in and steal his life?" Gideon asked. "That's so cruel, so sneaky, so devious, so dirty and unhanded!" He thought a moment. "If you take Dipper's place, would you object to me dating Mabel? For instance, if I did win her heart by beating her brother honestly and not forcing her in any way?"

"If I say no, will you agree to my terms?" Tracey asked, barely managing to disguise an eye roll.

"Yes," Gideon said.

"Fine," Tracey said, sticking out his hand. "Do we have a deal?"

Time: During Chapter 5, when everyone split up

Place: Gravity Falls Morgue

Candy knocked on the door.

The door opened, and Dr. Membrillo peeked out. "Ugh, go away, Candy. I've told you already: children do not belong in the morgue unless they're no longer breathing!"

"Please, Doctor," Candy begged. "There must be something you've found."

"If I say yes, will you stop making up false stories about how your biology teacher offered you extra credit to sit in on an autopsy?" Dr. Membrillo asked.

Candy sighed. "Yes, Doctor."

Dr. Membrillo handed her a flash drive. "See that the defense gets these. My imaging software finally outputted these high-resolution three-dimensional images of the murder weapon. The finger span of the smudged prints is rather large, too large for Dipper Pines' tiny hands."

"So this proves Dipper didn't do it? Score!" Grenda cried.

"It doesn't prove anything except someone with larger hands handled this rock at some point," Dr. Membrillo said. "Be careful, young ladies. Neither dread, nor hope awaits a dying animal, but people await their end, dreading and hoping all." With that, he slammed the door in their faces.

"…That man could depress a hyena," Grenda observed.

Time: The day after the trial.

Place: The Mystery Shack

"I can't believe you let Northby sleep in my bed," Dipper complained.

"What was wrong with it?" Mabel asked.

"My pillow and sheets smell like cinnamon and lemon!"

"He wanted to take a shower, so I let him use some of my shampoo and soap…" Mabel explained. "Poor thing was so embarrassed about hiding out for three days without bathing. He still smelled better than you on any given day."

Time: The day after the trial

Place: The abandoned Dusk 2 Dawn

"One thing still bothers me," Quattro said. "When you testified, you kept making mistakes."

"Don't remind me," Tracey replied dully.

"I didn't get a good look at the body," Quattro began. "I had to run to the emergency phone to call the police and make the fake confession. But you were working at the scene. Why didn't you know Toby had been bashed on the side of his head rather than behind?"

"I…I just couldn't look at his head," Tracey said, eyes downcast. "It was Toby! It felt like only yesterday that I was accusing him of murder. The time I…you…we were Dipper Classic. I made the fake dying message, hoping someone would notice it was with the wrong hand. I knew if I looked at that horrible sight, I would collapse or throw up. So I turned my eyes away."

"It was too late," Quattro said.

"For us to do anything about it when we woke up," Tracey said. "But there was no reason Toby had to die. I wish I could let it go, but I can't. Dipper's sense of justice…my sense of justice won't stand for it. We aren't innocent, Quattro, but there are others who have to atone for far more than us."

Time: A few days after the trial, 5 PM

Place: The Mystery Shack

Mabel answered the door. She smiled. "Northby?"

Northby was standing on the porch, wearing a white collared shirt, brown plaid shorts, dark highsocks, his black loafers, a cream-colored ascot, and an olive green jacket. The ascot was pinned in place with a brooch featuring the North Star in colorless stones. "Do you like my new clothes? Pacifica picked them out for me."

"You look very charming," Mabel said. "What are you doing here?"

Northby was holding the loaner sweater and Dipper's loaned-out pants in his right hand. He held them toward her. "I wanted to return these after I washed them. And thank you once again. You went to a lot of trouble for me and you didn't know who I was."

"But you told me your name," Mabel replied.

"There was no proof I was who I said I was," Northby answered. "Pacifica never described me to you. My father made sure no recent photographs surfaced on the internet. I lost my ring."

Mabel gazed at Northby's empty left hand. "I'll get you a ring to replace it. It won't be as expensive, but I'll find a perfect one."

"Mabel, I'm flattered," Northby said. "But you're making a mistake."

"What mistake?" Mabel asked. "I like you!"

"I like you too, Mabel," Northby said. "But I'm not so socially ignorant that I don't know the significance of a lady offering a promise ring. You're a kind, considerate person and you deserve to be with someone who can make you happy. I'm not that person."

Mabel threw her arms around him, making him drop the clothes. "Never underestimate my power."

"The power of love?" Northby asked, confused.

"The power of Mabel," Mabel replied.

Deleted scenes:

Trucy is a yaoi fangirl, so I wanted her to share some yaoi manga with the girls. Phoenix naturally walks in on them.

Trucy: Daddy, this isn't what it looks like! Unless it looks like I'm corrupting innocent girls with my extensive yaoi collection, in which case it's exactly what it looks like. (gives her impish expression)

Phoenix: (picks up some hand-drawn yaoi and looks through it) Trucy, this is…shockingly anatomically correct. I'll just…take this. (Yaoi manga added to Court Record)

That Trucy has seen age-inappropriate material did make it into the final story, when she mentions that the Gremlobin eating Gorney was "way tamer than half the stuff on Sport of Crowns." And Phoenix doesn't allow her to watch HBO, but she can bypass the Parental Controls on the DVR.

Archibald Corduroy would appear during the trial, and Preston would get annoyed: "My daughter fulfilled your wish. What more do you want from me, you blasted phantasm?!" But I figured he was at peace, so he should stay that way.

Originally, Dipper and Roquefort had a conversation about Wendy, but there was no good opportunity for it. Nor did I have time to indicate Roquefort's interest in Wendy.

Roquefort: What will happen if you date Pacifica Northwest? You'll really impress her parents when you eat salad with the wrong fork.

Dipper: What, you'd think you'd be a better match for her?

Roquefort: Perish the thought. I don't have such expensive tastes. (gazes too long in Wendy's direction)

Dipper: You like Wendy?

Roquefort: No! (Dipper gives him a look) Fine, yes. Can you blame me?

Dipper: (after a moment) No, not really.

Trivia:

Preston was always going to be the murderer, but originally the victim was Mr. Poolcheck. Northby was immediately created and named, but he was possessed – though not by Bill. The possession idea was eliminated, but not before an idea that Mabel decides to drive out the demon the same way she got Bill to vacate Dipper's body. Unfortunately, Northby is not ticklish. She would then kiss Northby, and the demon would flee: "Ewww, mortal cooties!"

Epilepsy used to be seen as a sign of demonic possession, and in later drafts, Northby was not possessed but had epilepsy. So instead of genuine possession, it was just Sprott screaming that he was possessed. When Phoenix asks him about the night of the murder, Northby would have a seizure, as the medications at the asylum were administered daily rather than letting the patients keep them. Phoenix and Athena then go to Dr. Membrillo and claim Athena has epilepsy but lost her medicine bottle. Membrillo is suspicious but gives them the medication. They pass it to Northby and decide to hold off on questioning him about the murder until the medicine has had time to take effect. The epilepsy was phased out because his storyarc was depressing enough.

Preston originally told Pacifica that Northby was dead to explain Pacifica's paralyzing fear in "Northwest Mansion Mystery." But then that was too depressing, so Preston told her that Northby was at a strict boarding school.

Xavier Lesenfants' name isn't quite a pun, but it does mean "Castle of the silent." The connotation was "Savior of the silent." Enfants also means child in French.

Though not mentioned in the narrative, Nathaniel Northwest's son was named Vernon, which means alder. Alder trees are common in the Pacific Northwest. There's a superstition in Ireland that it's bad luck to cut down alder trees, because an angry spirit would seek vengeance and burn down houses. The sap is red-orange, and tends to dye the whitish wood red. The alder is linked with death and resurrection as well as courage. I thought the death/rebirth angle complimented the pine, which symbolizes immortality.

Northby and Pacifica were placed in two separate surrogates and born a week apart. Northby was born on May 10, Pacifica on May 17.

Northby's namesake, the North Star, is in Ursa Minor. The Big Dipper is in Ursa Major.

In my Ace Attorney storyline, Blackquill's family is quite distinguished. Blackquill and Pacifica? The mind boggles. But Blackquill was also born in 1999, like Pacifica and the younger Pines twins in the original timeline. In my story, "Poros," the Blackquills own a supernaturally powered diamond called the Venusian Diamond that can grant a single wish if you hold it when Venus is brightest in the night sky. So, yeah, Preston was hoping to use Pacifica's engagement to Blackquill to get his mitts on that diamond. Good thing Blackquill didn't bite, huh?
