Afterthoughts
It was rare Perry finished ahead of schedule, because Dr. Doofenshmirtz stuck to the same routine every day. But that one day, just as Perry had escaped Dr. Doofenshmirtz's trap, his own inator – Perry stopped memorizing the exact names long ago – exploded on him when he tried to fire it up.
After a sigh and some mumbling, and looking over his blueprints, the evil scientist admitted to having done something wrong, and did his little, 'Curse you Perry the Platypus' thing. Perry simply shrugged and glided off on his glider, glad for once at how ignorant his nemesis could be at times.
Phineas, Ferb, and even Candace were not home yet, which meant they had decided to build whatever it was they did today somewhere other than the backyard. He brushed it off, though. The boys knew what they were doing.
With a house all to himself, Perry could continue to act normal, not as a mindless pet. He would have watched a bit of TV, but he was fairly certain that right now, nothing that interested him was on.
So he thought. He thought, he wondered, he mused, all about one thing, or day, in particular: the day they opened a portal to the second dimension.
He wondered what would have happened if he had taken off a second later, or a second sooner, therefore missing Phineas and Ferb. Would they have still gotten to Doofenshmirtz to fix his Other-Dimension-ator, or would they have never met him and fixed the machine in the first place? And, if they did somehow meet the doctor, how would they have done so?
…What would have happened if the other Doofenshmirtz had not insisted on trying to prove he was, indeed, a secret agent? Would he have made Platyborg hit him a few more times? The platypus could have handled that without blowing his cover. Or…what would have happened if he hadn't leapt up to spare Phineas and Ferb getting punched by Platyborg? Would the other dimension Doofenshmirtz have given up, and left them alone? Or would they have gone to prison, for trespassing or something?
What if Phineas and Ferb – his Phineas and Ferb – had seen that broadcast, about how Doofenshmirtz would leave them alone if Perry turned himself in? Would they have been less mad, knowing he had done it for their safety? Would they have allowed him to leave at all?
And what if they hadn't come to rescue him? Would he have been made into a Platyborg as well, forced to hurt the ones he tried so hard to protect? What if…? What would have happened if…?
Perry found himself grimacing and clutching his head as the thoughts swirled. He took a deep breath, and then sighed. Why was he even thinking about it? It was all after the fact now – what had happened was done. He didn't need to worry about what could have happened, what might have happened, if certain things went a different way. That was the past, and this was the future. He just had to prepare for what lay ahead, and stop worrying about past events.
When Phineas and Ferb came home that day, they found Perry curled up, asleep on Phineas's bed. In his paws, he clutched something. Making sure no one else was around, Phineas and Ferb carefully pried the object – objects, they discovered – out of his paw. It was pictures of them, from their second dimensional journey. On the back of the last one, the one of Perry and Phineas hugging, was a little note, written by Perry.
Dr. D's invention worked, because Phineas and Ferb helped him on it. Other dimension was scary, as Doofenshmirtz ruled, and boys found out secret. We ended up having an amazing journey. They helped me beat the other dimension Dr. D, and I wish they could remember it all…
