A surprise visit at work, leads to a grander one for down the line.

Heinz Doofenshmirtz has always held a grudge against his family, which was his abusive and neglectful parents and the younger and his mother's favorite child Roger, who is his brother, and he rather stay as far away as possible from them. However, he is one day invited to a reunion, which could probably be a chance to fix his relationship with them and earn their approval.

Phineas earns his Emotional Bravery patch. (Or: he remembers when the world was taken over by pharmacists, even when the rest of the world doesn't. Isabella included.) — phinabella, canon-divergence

AU. The Turnpike Tavern is like home to Ferb. It's the perfect place for smoking, drinking, and everything else the young Brit enjoys. His life may seem like a long downward spiral, but he's content. At least he says he is. Phineas is living the high school dream. He's at the top of his class, has the perfect girlfriend, and plenty of popularity. He says he's happy. He's lying. PxF

A few days before the events of "Road Trip", Baljeet decides to take advantage of Phineas's absence to win Isabella's heart with an audacious construction of his own. But we all know how the course of true love runs - especially in Danville.
