This isn't the first kid who's asked if he's real, though at least this one is about the age he was when he was diagnosed. If he can even guess at a cat-person's age. It's a little less unsettling, but still is, because when a hallucination starts asking if you're the hallucination, things start to get dicey.

"I... I was just watching. I thought you weren't real." This is awkward. Does that mean all the other strange people he's seen are real too?

Or maybe this hallucination is just really convincing.

David pushes away from the wall and approaches one of the glasses on the floor and picks it up, inspecting it. It feels real. He throws it in the same direction she has been, flinching when it breaks against the roof.

He's starting to get more used to breaking glass since he's gotten here and mirrors have manifested as a new source of paranoia, but he still can't get the hospital out of his mind whenever he's the one causing it. The feel of a needle in his neck. He can almost feel it now.

He shakes his head, trying to get the thought out of it.
