A/N: Welcome to the fourth chapter everyone! Thanks for all the reviews; they were very inspiring. I think it's time to have a Ferb-centric chapter, so here it is!
Ferb is Phineas' polar opposite. Phineas was always in the limelight, but Ferb liked it like that. Most thought Ferb was in Phineas' shadow, and in a way he was, but Ferb didn't mind. Ferb was a listener. He was in the background, but that was his choice.
The future would bring many changes. Ferb would ultimately kick-start Phineas and Isabella's relationship by pushing the redhead into the girl. He would help them through whenever the relationship hit a snag. He would serve as best man at their wedding.
Of course, a week after being pushed by Ferb, Phineas tripped his brother, causing him to land on Vanessa. Isabella's advice would save Ferb's relationship with Vanessa all too often. Phineas and Isabella planned the wedding.
Phineas and Ferb grew up to be inventors, friends, partners, and neighbors. They were, and always will be, brothers.
