@XxFellsingxX It'd be likely if he was contacted by someone requesting his business; soul contracts n' such. If Moon Man is okay with the blackmail thing I'd think it'd possibly be more likely. Although he is still somewhat human, Hush thinks he's superior to pathetic mortals and doesn't love to socialize with them unless it's for work. Or his patron tells him to.
Alright. To be honest, I just have this hilarious imagine of Hush ordering a coffee and when he gets it, it has a ominous warning written in felt tip pen and it's like:
Hush: Excuse me, I've got an ominous warning written on the side of my coffee.
Kendra: Oh wow weird how did that get there
Hush: What do you mean "How did that get there"? You were the one who served me this coffee.
Kendra: You sure? Could of been anyone.
Hush: ... you literally served this to me a minute ago.
Kendra: Buddy, I've worked here for a year now, do you think I remember everyone I've ever served a coffee to?
Hush: ...
Kendra: ...
