I raise the flop. If he's calling you it's beacuse he has some kind of out to chase. I don't like people having outs in my pots. The pot's fairly big on the flop already, and you're technically protecting a pot even larger than that, since UTG should pay you a few more bets when you've got a ton of equity. I think protecting your hand in tiny pots is over-rated dogma, but once they get passed that 4-5SB mark there's really no excuse for it. Protect your hand.

On the turn who knows.
