It depends, sort of, but... honestly, I just bring some of them home. If it's not clear what's keeping them attached, or they don't know, then it's hard to help them pass on properly-- in that case it's best for them to haunt somebody who can at least see and communicate with them until we get it figured out, yeah?

[A slight shrug, there, his expression just a bit sheepish-- he knows it probably sounds kind of crazy, to just invite ghosts into his own house, but as far as he's concerned it really is the best way to go.]
