Sea?!

dirty little animal

Like I mean think about it, he seems genuinely surprised when Jinx hugs him after revealing she stole the hexgem, like that is bro's DAUGHTER that he loves with all his heart and I feel like he genuinely doesn't expect her to, or even believe she does, love him back. At the tea party confrontation he doesn't try to appeal to her with "I love you, look at all we've been through together" etc., he takes the angle of "I'm the only person who has never and would never abandon you." As if he thinks his loyalty is the only thing of value he alone can offer her.

His life experience doesn't really contradict this, Vander viciously betrayed him which would perhaps make him think he'd never actually loved him in the first place, Sevika only sticks by him because he's good for Zaun and would kill him without hesitation if that ceased to be the case, he has a pretty amicable relationship with Singed but it's also notably transactional with Silco first being a test subject and later helping to fund Singed's experiments, and pretty much everyone else he interacts with is kept in line by fear, addiction, or both.
