"It's okay if you feel that way," Peter blurts out.

Only once he's said it does he feel his face flush with embarrassment. He'd admitted to Quill back on Father's Day that he considered Tony to basically be the closest thing to a father he had.

And though he can't quite bring himself to admit that to Tony's face, he can at least let him know that it's okay.

But when there's no immediate response, Peter immediately scrambles for cover:

"... if you want to," he finishes.
