In my Pokerroom experience, people bet/3-bet the flop against a steal a hell of a lot, especially on a board like this, and often with nothing/close to nothing. I think the villian is thinking (rightly) that you're weak since you were on a steal. That being said it is hard to put him on a hand. probably call flop and bet if checked to on the turn. If bet into UI on the turn, reevaluate, but probably drop it.
