He feels sick, hearing Peter sound so lost and knowing it's his fault. Jason wasn't trying to hurt anyone, and least of all the people he's hurt the most in all of this; he doesn't even know what he was trying to do, except that fixing anything didn't seem doable and living with all of it broken seemed impossible. He wasn't thinking about after for anyone else.

He hesitates, lets the silence stretch out for a second; the urge to curl up is strong enough that Jason stops trying to hold back, drawing his knees up to his chest as he finally says, "I -- fuck, I'm sorry." He doesn't to sound as miserable as he does -- he should be stronger, let Peter be broken right now, but obviously he's not strong enough anyway, or he wouldn't be here right now.
