Your...bloodtype? [He looks lost.] Could you have germs in your blood that are preventing you from using your abilities?

[He doesn't even blink when Dipper waves his hand at nothing, having seen enough to not find it odd.]

Likewise. [He nods, but he doesn't keep his attention off of their surroundings for long. It would have been helpful if one of them could manipulate the dream, and Gil supposes neither of them have the upper hand, but staying on guard still makes him feel better.]

Maybe you've met my friends. I've seen some of them here. [More like his family, at this point.]
