He's not sure how to deal with her being all... friendly -- not like he's rejecting it. It's not exactly possible for him to reject offers of friendship like this anymore. See: Garth, and all the times he let Garth hug him, and especially the twenty seconds he let himself like it. No, the real issue is that she's just throwing it all at him so fast that he's trying to keep up, which wouldn't be a problem if he weren't still so shocked and maybe touched (not on the face, but in the emotional way) that she... cares so much. Or at all.

"Too soon?" he says, scoffing and brushing it off because that's how he has to approach this. "What, are you going to tell me megaporn closed? Because I know that one already."

RIP.
