Discovery

When Doofenshmirtz finds out he has a son, things get complicated. Even more so when he finds out who his son is, and what happened to him. I DON'T OWN PHINEAS AND FERB, DON'T MAKE ME DO DISCLAIMERS FOR EVERY FREAKING CHAPTER. Rated T for romantic moments and some language. I WILL NOT UPDATE UNTIL I GET AT LEAST ONE REVIEW!
