He was actually serious about the threat to chop of his dick (per Hanse on twitter) so he may have been serious about breaking his ribs as well. It’s just that when he doesn’t go through with his threats, he makes a joke out of it to lull the other person into a false sense of security. He 100% is a fucking psychopath though. He definitely gets off on pure raw sadism and I’m not sure how he and Rian are supposed to compromise on their respective tastes in bed.

I don't know that Enzo is gaslighting anyone. That really might be his version of "dirty talk" and this is his version of a normal relationship.
Which makes him even more of an absolute fucking psychopath.
