Hello, everybody, this is Marissa Flynn signing on. So, just a couple quick notes about this story:

After much consideration, my OC, Marissa Flynn will not be a part of this fanfic. I'm going to experiment with myself and see if I can write a multiple chapter story (movie if I must) without my OC.

So without further ado: I own ABSOLUTELY NOTHING EXCEPT THIS FANFIC

Warning: this fanfic contains spoilers to both 'Night of the Living Pharmacists' and 'Tales from the Resistance'.

Review and enjoy.

Phineas tossed and turned, wincing and whimpering in his sleep. One wince after another, "No...no...pharmacists… Lots of me. No!" With another wince, he whimpered once more.

"I don't wanna be a pharmacist...no! Leave me alone," Phineas whimpered in his sleep and he bolted awake with a scream, "Aah! Oh...guess it was just a nightmare again. Man those pharmacists were scary."

It had been almost a week since the pharmazombie apocalypse had been barely prevented. He'd been trying since then to remember what it is he'd forgotten, but to no avail. The pharmazombies still haunted his nightmares, but he couldn't let Ferb and the others know. No way hosea. He sighed glancing at Ferb who had been snoring. Chuckling, he approached his brother and tapped his cubical nose causing him to snort and turn the other direction so as not to snort anymore. With a small chuckle and then a sigh, Phineas returned to his own bed and laid down.

"You'd think after a week I'd gotten over it, but I haven't. It's still fresh in my mind, and it haunts me. Why is it still so fresh in my mind? Bad enough I watched Mom, Dad, Candace, Buford, Baljeet, Candace and even Ferb be transformed into those freaky pharmacists who apparently were based on that other pharmacist...poor guy, so basically watching everyone I ever cared about be taken away from me except Isabella (although I have a feeling she'd been changed too after I had but luckily been able to push the button first), but every night all I hear in my nightmares. 'Lots of me...Lots of me'. Ugh! Why can't the nightmares just go away?!" he thought to himself.

Phineas smacked his head against the pillow, turning over and falling into an uneasy sleep. He had thought about telling Ferb or Candace about it, but decided against it. He'd been doing such a good job of masking his anxiety for a week now...why stop there? He only wished it would go away, but something in him kept pushing him back into the event, like he'd forgotten something important or something big was coming again…

Phineas had no idea how right that part of him was…

-Meanwhile in the Second Dimension-

Phineas was laying in his bed, staring at the ceiling while having the thought of Doofenshmirtz rising to power again now that he was evil again and with him, Charlene and Vanessa having gotten away, etched into his brain. He looked over at Ferb who seemed to be peacefully sleeping. He sighed, not wanting to wake him. He could feel Perry the Platyborg laying at the foot of his bed sleeping peacefully now that he wasn't an evil cyborg anymore. He listened over to hear Candace doing her pull-ups again. He figured he may go talk to her.

"Candace?"

Startled, Candace grabbed her staff and used the point of it to pin Phineas to the wall, upon realizing it was only her brother, she softened her glare, and she lifted her staff away, "Oh, hey, Phineas. What're you doing up?"

"Do you think Doofenshmirtz will come back into power since Charlene and Vanessa got away with him? I don't want him to take summer and everything fun away again. I mean we just got it back!"

"I know, Phineas, and we're not going to let that happen again. Now that we're older and have the Resistance and OWCA back, we'll be ready for them this time. If all else fails, we can ask the other dimension Phineas and Ferb for help," Candace assured her brother.

Phineas accepted this, smiled, and he went back to his room, but he was startled to see Doofenshmirtz in the streets alone, but he wore a white labcoat and his hair was a lot messier. His eyes seemed to be out of focus too.

"CANDACE!"

-Two days before…-

"Heinz, are you sure about this kid? I mean he's not even of this dimension," Charlene complained.

"Trust me, Charlene, he'll be a threat to us if word gets out. However, he won't be able to stop us this time because he's going to join us," Heinz smirked.

"How do you propose we do that, Dad?" Vanessa, their teenage daughter asked.

Heinz smiled evilly at his wife and daughter, "Because a little birdie told me he doesn't remember anything to do with me or this dimension and I know exactly how we'll scare him into it."

With that, he produced an image, taken from a security camera at the Danville Water Tower (first dimension of course) of Phineas sacrificing himself to save Isabella from being turned into a pharmacist.

"And I know just how we'll do it," he cackled insanely as Vanessa and Charlene glanced at each other.
