Peter can't help a soft, quiet laugh of amusement at that. Not that it's funny that poor Luz is having hallucinations, it's just that she has a way of wording things that's humorous, and it does tickle him.

Though it's definitely raising his levels of concern, and he moves to let her in, closing and locking the door behind her.

"As far as I know, I haven't turned into a giant blob head. ...Though I guess in this place, I shouldn't discount anything from happening."

There's a little grin as Peter leads her down the hallway, toting the basket she'd given him. He thinks about heading to the living room where they can sit down nice and comfortable, but.... there's the risk of bumping into some of poor Falco's... purple goo.... Peter's debating it as he starts moving up the stairs.

"You wanta come up to my room for awhile? It's not a mess, I promise. No ants either."

That's a joke... an ant-related joke, because what else do you do with someone who supported you while you vomited ants that one time?
