Note Hannibal can and will use anyone--including Charles, Guppy, and others:

Sunshine/Little!Rae - they're best friends; if I tell her anything, she'll tell the bar
Fakir
Duck
Mia
Oswin
Lucas
Lohengrin - Has already attacked him
Poins
Yugo
Karkat
Nepeta
Punie - ?

Questions: Can I assume these people will be subject to the same hurtful emotional "play" he does with me? How many of them does he know - and of those, how many does he know speak with me? How many of them does he find "rude"? Am I the only one who suspects anything?

He'd be quite capable of violence, should he choose to use it, but will he?
