Sani mostly keeps to himself, though he's tempted on occasion, he doesn't bother entertaining the idea of taking anyone on the crew, especially other people's pets, not worth getting in trouble. He's largely given up on John because he doesn't make that much trouble anyway. I imagine he's friendly enough if anyone wants to talk to him. He's also inclined to help out on the ship when needed, and he doesn't duck out on fighting when it needs to be done. I imagine when he does take slaves, he keeps them tied up and out of the way, and unlike John I imagine they actually stay tied up and out of the way.
