History TearJerker / PhineasAndFerbTheMovieAcrossThe2ndDimension

** The fact that Perry didn't break cover as the boys unwittingly helped an evil scientist and become trapped in another dimension, and only just does so when they've been cornered, only serves to make Phineas even angrier.

* "I thought you couldn't spell 'platypus' without 'us'." Though, after a pause, Ferb makes a reply that makes this more of a funny moment.
* "Hey, where's Per... oh, that's right."

-->'''Doofenshmirtz:''' [[DisappointedByTheMotive That's... That's it?!]]
-->'''Doofenshmirtz-2:''' What do you mean?
-->'''Doofenshmirtz:''' ''That's'' your emotionally scarring backstory?! That's your great tragedy?! Dude, I was [[RaisedByWolves raised by ocelots]], literally. [[IHaveNoSon Disowned]] by my [[AbusiveParents parents]] and raised by Central American wildcats, and you're telling me you lost a ''toy train?!'' That's it?! That's all you got?! Really?! I had to work as a lawn gnome, [[HumiliationConga I was forced to wear hand-me-up girl's clothing]]... ''NEITHER OF MY PARENTS SHOWED UP FOR MY BIRTH!''
* Before they fire up [[spoiler:the memory eraser]] on the gang, Monogram is clearly shown with tears in his eyes, which he refuses, and, as a CallBack to an earlier episode, claims to be "[[Recap/PhineasAndFerbVoyageToTheBottomOfBuford sweating from [his] eyes]]."
* Phineas learning the real reason why Perry kept his secret from them (so he would never leave them), and clearly [[JerkassRealization realizing what a jerk he had been to him earlier]].

* "I Walk Away".

** Even ''[[TheStoic Ferb]]'' (both of them, in fact) gets teary-eyed at that part as pictured above.

---> '''Phineas''': Was that evil guy right? Were we just your cover story? [[WasItAllALie Were you ever really our pet or part of our family?]]

[[caption-width-right:350:You know it's bad when even Ferb's tearing up.]]

-->'''Doofenshmirtz:''' That's... That's it?!

---> '''Phineas''': So not only have you been leading a double life this whole time, but you sat there and let us help an evil scientist open an evil portal into an evil dimension, and you did nothing to stop us?! (...) No, no, that wasn't enough! That's when you should've put on your little hat! Not now, after we've gone through it into this mess!

** Their reactions. Ferb actually takes the whole thing in stride but Phineas is completely outraged. Perry actually looks upset and awkward as Phineas chews him out with Ferb even trying to jump to Perry's defense but Phineas isn't having it. It's upsetting given how close those two are.

* The final scene mostly [[Heartwarming/PhineasAndFerbTheMovieAcrossThe2ndDimension heartwarming]], but the last [[http://images1.wikia.nocookie.net/__cb20110809162959/phineasandferb/images/2/22/PnF_AT2D_14.jpg photograph]], with Phineas and Perry sadly hugging...
** Made even more upsetting when you remember that Phineas had been the most messed up over learning he was a secret agent.
