$3.30 rebuy, pot sized bet, get him to call. you have an over pair in a rebuy. players will play any draw, any pair (even bottom pair). If your behind, then so be it, but value betting in a rebuy is a must, donk play galore in these. Too unpredictable to put any player in a rebuy on ANY range of hands (just because he hasnt done much since his buyin, does not mean he has a monster, even though it may suggest he's not playing bottom pair).
