Going through all of Season 4 and forcing myself to watch every grueling episode. Truth be told, this season wasn't that good which is probably why the show got canceled. Even then, I do wish that NBC let them have their wrap-up movie.
Fic about Nathan's death and funeral. I've always loved Peter's eulogy scene, especially the planes and Peter's smile at the end.

"I need you to help me. Now pull yourself up please."

Nathan. It was always Nathan. Nathan the popular one. Nathan the valedictorian and jock. Nathan the senator. The spotlight of attention that didn't have enough time for his little dreamer brother Peter. Nathan the backstabber, going around and breaking everyone's hearts.

"You're going to have to carry on for the both of us Pete, okay? You tell mom I love her. You take care of Claire. Fight the good fight. You've always been everything that's good in the world Pete."

"Nathan…"

But a lot had changed in the past few years, shaping and molding him into the man who'd died for his country. Who'd died the hero, like he'd always dreamed of. And Peter was living proof of it Nathan's legacy. Peter the conscience –the one who kept him grounded.

"And I got a feeling the world ain't seen nothing yet."

But Peter should have seen it. He was always the first one to know when something was wrong with his brother. So why not this time? Was he getting slow? Was it because his power had been reduced to single mimicry? If he'd seen what would happen ahead of time maybe this whole mess wouldn't have started. Maybe… maybe Nathan would still be alive.

"I can't do this without you."

Peter had always wanted to be a hero. The nurse, the empath, the paramedic. The one who made the difference. But he couldn't even save his own brother.

"You can do anything Pete. Anything. Remember that."

So when the fighter squadron passes overhead and the lone plane breaks away from formation, Peter smiles. Because he can see his brother up there, giving the pilots a run for their money. He can see him flying in the crisp blue air.

And that contrail is spelling out "fight the good fight."

"I'm ready brother. For whatever comes."
