I'd consider raising the donk bet on the flop, if for nothing else it lets you know if you can get free cards off the stranger when you are in favorable position. As for the call I'm leaning towards Sharpie's reply regarding 5.5 to 1. With expected value you could argue even money but how sure can you be about your outs being clean on a stranger? With the calling line I would consider going passive and showdown with improvment on the turn. Thinking more about it, raising the turn is a strong play considering that if he is new to the table its hard for him to play back at you without two-pair, in which case if his hand was at least that strong on the flop, why would he donk bet into the aggressor (unless he is supernewb for 2/4 which does happen). Going passive and showing down gets information, but the info doesn't seem that important and the price seems high for it as well as missing bets for value.
