Being the fangirl that I am, I shall now make my contribution to the various fics that have been written since the wonderful movie, Phineas and Ferb: Across the 2nd Dimension.

Keep in mind that I do plan on writing some sort of big story for this, but first, I need to find time to write those ideas down. For now, though, this is just a collection of oneshots, based on what I think happened after ATSD. Enjoy!

After the Fact

After the Fight

Candace seemed a little woozy as she came in the door, followed by Phineas and Ferb. Linda arched an eyebrow at this, and the fact that they were coming in so late in the day. "Hey, kids," she greeted them. "Did you have a fun day today?"

Phineas frowned at the question. "I…I think we did," he responded hesitantly. "I can't seem to remember what happened today, other than the fact it's the anniversary of when we got Perry."

Candace nodded. "Yeah…there was probably something huge for you to bust mom," Linda smiled a little at that, "but now…I just can't remember."

By this time, Perry had walked in, and made his usual little chatter. "Oh, there you are, Perry," Phineas said, as usual. "Did you have a fun day today…whatever we did?"

Perry just chattered in response, and Linda smiled. "Well, kids, dinner's almost ready. Whatever you did, I'm sure you had fun."

Phineas just shrugged in response as he went to sit at the table with his sister and stepbrother. From where he was, Perry suppressed a sigh. What a great day they did have…

"Goodnight, kids."

"Good night, mom!" Phineas replied as Linda shut their bedroom door. Perry was already curled up, asleep – or at least seemingly asleep. Phineas watched their pet platypus for a moment before shrugging to Ferb as they pulled off their invisible helmet-head systems.

"Pretty cool how our helmet-heads are resistant to amnesia-rays, huh, Ferb?" Phineas asked, grinning. Ferb gave a thumbs up, but as Perry heard this, his eyes snapped open wide.

"Yes," Ferb agreed. "But, what do we do now?"

Phineas shrugged. "Just act normal, I guess," he replied, scratching Perry's head absentmindedly. "We don't want to risk that guy…Major Monogram, I think? – finding out we remember today."

"Speaking of which, are you going to tell Isabella she kissed you?" Ferb inquired. Phineas blushed brightly at this.

"Um, no," Phineas decided. "If it happens later on, I'll just have to act surprised."

Ferb smirked at this, while Perry's brown eyes darted from one boy to the other. They shouldn't have remembered, they shouldn't have! This could be dangerous for them, especially if they remembered Dr. Doofenshmirtz, and decided to try and help Perry!

Phineas paused in his petting Perry, seeming to realize the platypus's distress. "Don't worry, Perry," he whispered. As if reading his thoughts, the red-haired boy added, "We won't try and intervene in any of your missions, unless we know it's life or death. OK?"

Perry hesitated, wanting to keep up the act of 'mindless pet', but if they knew…he chattered in reply, hoping they understood that he was saying, 'As long as you keep your promise.'

Phineas and Ferb smiled simultaneously, and Phineas's eyes twinkled. Perry knew what that twinkle meant. "Hey, Ferb," he whispered as he shut off the light. "I know what we're gonna do tomorrow…"
