i need to feel needed (and i need it more than i let on)

"The world moved on without me," Peter finally says. There’s no inflection in his voice, no emotion, like all of his feelings had turned to dust at the same time he did and never quite returned. "The world moved on without me, and.. I don’t know if it wants me anymore."Tony swallows past the sudden lump in his throat, words failing him in a way he didn’t think was possible, because how do you explain to someone - to Peter - the grief, the overwhelming grief and anguish and heartache that the world had to face when they weren’t there to see it? When they can only see the aftermath?-Peter doesn't really understand just how much Tony grieved during the five years he was gone.
