A/N: Who else was surprised Bill showed up? Cause I was. Sorry it took so long, life and annoying writers block got in the way. I hope you like the conclusion of my three parter. And to answer akuma's (Guest's) question,

Bill doesn't really have a set character in the AU. Sometimes he's a hunter, others just give him a body or make him look more frightening. I sort of combined them a bit cause I think they're all great ideas.

Anyway, long author's note is ending now. Please Read, review, and enjoy! Disclaimer: I don't own Gravity Falls, and no, I have no idea what moonstone would do to other media type werewolves. I'm taking authors liberty here, okay?

Wendy streaked across the lawn and into the dark woods. The sharp smell of fear and blood and sweat guided her. Paws thundered against the moldy leaves and kicked up dirt and residue.

The scent led her to a clearing, the smell choked her and blinding anger rose up like a great beast when she saw what had caused Dipper to scream.

A strange creature was tugging the deertaur after him by a noose of rope. The preteen's bandages were turning pink with reopened wounds and his face was scratched and scraped as if he'd fallen upon it.

The creature was tall with a strange yellow triangular head, a taunting voice that spouted insults and jeers as it tugged the poor boy after him. Words of skinning and lessons and far more horrible things then she dared imagine.

Wendy saw red and she rocketed forward, growling and barking no longer quite aware of anything else other then killing the thing in front of her.

The creature turned and it's eye widened in shock as she lunged and landed upon it with a thump. Her claws ripped and tore, snarling and snapping as she attacked.

The red faded with the thumping of something deep inside her and when she came out of her haze of anger, the pulp before her was no longer living. Wendy's eyes widened as she saw what she had done and she stumbled backwards in horror.

A whimper alerted her to the presence of another being and she remembered why she had killed the thing in the first place. Dipper sat upon the ground, his eyes wide in astonishment? Shock? Fear?

"W- Wendy?"

"I'm so so sorry... I- I didn't..."

Dipper whined again and scooted closer, "Can you just h- help me home?" Wendy nodded and turned to help him, with great hesitance, she reached her arms down to lift him and to her great surprise Dipper practically leapt into her arms.

She shakily stood on two legs, she preferred four most of the times, and Dipper rested his head on her shoulder.

After a few awkward minutes of silence, Wendy asked, "Is it dead?"

Dipper glanced briefly back at the mess and then swallowed, "I doubt it, Bill's... er, it's a demon. He's probably just recuperating."

Wendy quickly walked away.

The crunch of leaves beneath canine legs reigned for several long minutes before Dipper began, "You know, the deer fight or flight instinct is getting really annoying."

"It is?"

"I get this weird feeling like I need to run or else something horrible is going to happen and there's this feeling that swells up. I can't hear anything and suddenly I'm running away. It's really hard to control the stupid thing."

"Well, at least you don't lose your humanity every time the moon is full."

"Can't argue with that, Wendy."

"You'd better not."

Dipper gave a slight smile before cracking a large yawn. His eyes kept drifting closed, the adrenaline fading and making his limbs bone weary.

About half an hour later, the shack was in sight. "Hey little dude, there's the Mystery Shack."

No response.

"Dipper?" She glanced at where his head had fallen, his familiar pine tree hat covering his eyes.

She took a clawed hand and gently lifted the hat off and found him to be asleep. Her first thought was to sigh in exasperation, but seconds later a relaxation dawned.

He trusted her enough to fall asleep. He trusted her, Wendy the girl- er, wolf, who'd almost killed him, enough to fall asleep on her.

Wendy decided to let him sleep. Unfortunately her movement to place him on the deck caused Dipper to rouse. He blinked at her and then his eyes widened as he realized he'd fallen asleep on her.

He sat up like a shot and rubbed his eyes, "Sorry, sorry, I didn't mean too."

Wendy laughed, "It's all right dude."

Dipper tugged his vest and then he grinned, "Hey, I went out into the forest for a reason!"

He pulled a sliver glowing stone from his vest and placed it in Wendy's small paws.

"What's this?"

"Moonstone, I think. You won't turn feral at the full moon if you keep it with you."

Wendy took the smooth oval stone in her furry palm. "Wow... That's... That's actually... Thanks a lot, Dipper, thank you!"

Dipper squeaked as she wrapped him in a hug but he quickly recovered and hugged back. When he felt her press a kiss to his forehead he turned a bright red. Eventually Wendy coughed and Dipper let go.

Dipper kept shooting sideways glances at her as they sat together. Grunkle Stan poked his grey rocky head out of the store and observing them watching the moonrise, quietly backed inside.

Morning came with wolf and deer, predator and prey, Wendy and Dipper asleep on the porch under the sky.
