"Perry the Platypus, why are you here? I'm not doing anything evil. I haven't even thought about doing evil since yesterday." Doofenshmirtz stared at Perry, who had just bashed open his door. Perry looked around. Nothing. No evil. No inators. Only Doofenshmirtz in the same labcoat has yesterday. The bags under his eyes were even larger than normal.
"See? There's nothing here!" Doofenshmirtz explained, "Nothing. Just me. And Norm over there, but his squirrel is on vacation."
Perry pointed to the door, asking if he should leave.
"Go, stay, whatever. I don't care. It's not like I'm doing anything. Just sitting here alone in the dark."
Perry glanced at the door and back at his nemesis. He walked to the door, but instead of going through the doorway, he closed the door in front of him. He walked over to the table Doofenshmirtz was sitting at and sat on the other end. Perry looked around, then smiled at Doofenshmirtz awkwardly.
"You're staying?" Doofenshmirtz asked. Perry nodded. "Thank you, Perry the Platypus. You know, this reminds me of a backstory from my childhood." Perry narrowed his eyes. Of course it does.

Stacy, Jeremy, Albert, and some of the other neighbor kids had gathered to watch Phineas in hyper drive.
"It doesn't even look like a jetpack," Albert commented.
Irving automatically defended Phineas, "Of course it looks like a jetpack! Right there is the..." Irving tried to make sense of Phineas's creation, "Well, that there is...over there is clearly...I've got nothing."
"Why is Phineas acting like this?" Baljeet asked.
Candace, Ferb, and Isabella answered together cryptically-
Candace: "Once in a while he gets this way."
Isabella: "No one knows how it starts, or how it ends."
Candace: "He never remembers any of it."
Ferb: "It's like he's possessed by something."
Candace: "This is the fourth time it's happened."
Isabella: "I hoped I never saw something like it again."
Baljeet interrupted their cryptic talk, "But what exactly is happening? Is he going crazy?"
Candace glared at Baljeet, "Phineas is NOT crazy."
Stacy huddled close to Candace, "Are you alright, Candace? I know how much this scares you."
Candace couldn't keep her eyes off of Phineas, "I don't know. I hoped by trying to keep the boys from doing crazy things this summer I could stop it."
Ferb crossed his arms, "That obviously didn't work."
Candace lost her temper on her brother, "Well obviously neither did letting it all out every day!"
"Candace!" Jeremy and Stacy shouted in unison, trying to soothe Candace.
Jeremy held Candace in his arms, "It will be alright." He looked at Stacy for encouragement.
Stacy couldn't give any, "He almost didn't make it out of the last one."
Isabella burst into tears, leaning on Ferb's shoulder. Ferb hugged her, still watching Phineas.
Phineas just kept at his machine. A huge smile covered his face and his eyes were wide, barely blinking to moisten them.
