The hand Dipper shakes is firm enough in terms of grip. It's also just a little blue-tinged. Just like last time, Fiddleford has arrived corrupted and seems to have a harder time shaking it than most. He is dealing with that by resolutely ignoring it! It's fine!

"That seems like the next logical thing. I figure I want a good four walls and a roof between me and most of this place."

He has a sinking feeling that anywhere a Pines might recommend to him will not be all that un-haunted. If Dipper is anything like his Great Uncle Ford then his idea of a good place to stay will be very skewed. On the other hand, maybe the Pines common sense (or lack thereof) skips... uh... every two generations?
