AA help - $25 Pokerstars

I have played 50 hands at this table. UTG is pretty LAGGY. So far I have remembered him showing down once: he called a $2 raise with AJo from the big blind and won the hand.

I need help on what to do on the turn in this situation given the only read I have on UTG. He obviously called a strong re-raise on the flop, is that enough to stop me in my tracks?
