A/N: Long story short, I was having a sleepover with some of my cousins, and my sister was watching Disney Channel with them. Of course, with the new movie coming out next week, every commercial break had two previews for it. No joke! So, my favorite part so far is Phineas throwing the pamphlet. Only because I like angry Phineas (which we've only seen three times now {one I mention in this, the other is in the Christmas special}). So, the plot bunny bit me. Hard. Despite it being imaginary, I think it left a mark. So, enjoy this drabble!

Oh, and did anyone else notice how it's odd that Phineas appeared to have Perry as a toddler, but the movie starts with their 5-year anniversary of having him?

EDIT: Alright, people keep asking me about the time he was angry in the Christmas special (which I find odd, since that one I knew right away, while I had to look up the "Summer Belongs to You" one), it's not really angry as much as really annoyed right after the song "Where Did We Go Wrong?". I just noticed that both of those times, it seemed to be extremely annoyed for a couple seconds, while in the movie...real anger for a while! Oh, and I MIGHT add more after the movie premieres...

Disclaimer: If I owned Phineas and Ferb, the movie would have already premiered and I would know when Phineas and Isabella are supposed to kiss.

Phineas couldn't help but be amazed at the alternate dimension. And it probably wasn't even the only one! That, however, was something they couldn't discover at that moment. First, they wanted to explore this one a bit. Especially since Dr. D was famous here. Although, he couldn't help but notice that Perry seemed to be acting strange…He even bit the doctor when he was petting him!

When they finally found the alternate dimension version of the Dr. D, he realized why. Apparently, Perry was a secret agent who was nemesises with the doctor, and that's where he went everyday. He just couldn't believe it. How could he not figure it out? [1] After all these years...and Perry never even gave a slight hint! Soon, his shock turned into anger, which was something he rarely had in his life. In fact, the only other time he could remember being genuinely angry was when Candace wouldn't get on the tricycle so they could get home before sundown on their trip around the world.

Even later, when all of the shock had worn off, the anger was still there. Sure, some slight confusion entered his mind shortly after Perry, or "Agent P" as they had learned he was also called, saved them (again) and they were on the skull thing with the horn and antler, although it left when he was handed the pamphlet.

He would never forget the sense of betrayal he had when he learned about Perry's double identity.

[1] Gee, I wonder why!

A/N: Sorry, I was mean in my little comment, but I'm under a hormone attack, alright? Oh, and the only reason I didn't put any dialogue or details in is because I have a SLIGHT issue with that...So. I'm gonna go hide from an OC that's mad at me, and you can press that pretty review button!
