Mick here is the thief Ray tries to feed vegetables too. So far he's been unsuccessful.
I have Mick sort of on the borderline between staying with the survivors and wanting to join the saviors. He would THRIVE in an environment like that, though his loyalty to Ray and maybe a few others keep him at bay. He also wouldn't do well if they ever tried to rule him with fear and intimidation, though if offered the perks that Negan's inner circle receives would probably be enough of an incentive for him. So depending on how much she's around, I could see her planting ideas into his head about switching sides.
