Feeling immeasurably exhausted, Peter leans back slightly, placing his weight behind him on the palms of his hands. Whenever things got too much, even for him, Peter looked back and forced himself to remember what Nathan had said to him. That he's always been everything that's good in the world. And granted, he didn't believe it every day. He couldn't. Not when he felt that he barely made an impact, that he'd done more wrong than right. But Nathan had believed in him, Nathan had believed that he still had enough good left in him to keep going, to keep doing. If there was one thing he had to live up to, it was that, even if the memory alone hurt more than he could take.

Looking off somewhere else, Peter swallows everything back, his expression softening back through grief. "I have to try." Nathan's words were his own to keep though; an exchange between his brother that he would never share. But he could pass along the mentality and use the words to remember there was a time where he'd found it so much easier to find the good in other people, too.
