Oh, oh jeez. Peter reaches over and pulls Miles closer to himself in a half embrace filled with as much apology as he could radiate through gesture about how sorry he was to bring up family at a time like this. His mother's gone and they're stuck here alone and freezing because of something stupid Peter did.

His gloved fingers dig into Miles' shoulder as he fights not to cry because damn it all, this is his fault. Not Miles'. The younger Spider-man doesn't deserve this.

"Come on. We c-can't give them reason to worry, yeah? We gotta s-s-stay positive." What could he do to help? Peter doesn't know. But after a few moments he starts rocking back and forth ever so slightly still holding on to Miles. The motion is comforting for him, maybe it'll help out his Spider-Bro too.
