Don't have too much set in stone for Hugo and Leonhardt here, but have a couple of ideas.

I don't object to a repeat of someone walking in on Leonhardt while changing like Grune did last draft, or in the shower, or whatever! and he'll likely fall victim to weird tasting food. Definitely good timing on something like that because he's been a stubborn git about getting his DP removed.

Hugo I have a few ideas for, basically some of the following:
-End up somewhere where he can't just easily take a teleporter back.
-maybe he'll appear to have some stereotypical demon features to freak him out? Though considering the truth and lies I gave for him, may do this on the first.
-Otherwise am pretty open, just nothing that would seem outright dangerous because I don't need him going batshit insane quite yet.
