[Oh, Okabe's aware how terrible he looks; he's looked in a mirror or two in the past day. To his credit, he only groans a little when Dipper says that, but lights up at the prospect of being taught a Special Handshake - fun chuunibyou shit, yes!]

[He lets himself be led through the handshake, nodding with approval the whole way through. Yes, this is solid! It's fun, and the charade gives him confidence, just like being Hououin Kyouma for awhile. When he steps through the threshold, it's the first time his hand has loosened from the vacuum hose in an hour.]

[He'll keep the handshake safe in his head for later, but for now...] You're doing pretty alright in here, you know? I never thought these- [he motions to the wards] -really worked, before I saw it for myself. But I never thought ghosts were real, either, so there's that.
