foxwoods 20 hand, tough spot, confused read

[LoosenUp]

Foxwoods 20 full, slightly tougher than normal.

utg solid 2+2er, I have played with him some but not to much. From what I can see is a winning tag that can get slightly out of line if running good, although mostly in position

SB a younger asian on the lag side, no history with him, but in the 2 hours I have been there hes gotten out of line a couple times.

hero in the bb with A4s

utg raises, folded to sb who calls, hero calls, 3 to the flop

Flop
2 2 4 two hearts
sb bets out, hero raises, utg cc, sb calls

ok, utg cc confuses me at this point he could have AK, AQ, AJ hearts maybe AK off. Although, I got to think he would fold all non flush draw broadway hands

If its an overpair I would think that he would 3-bet, actually along with the above hands, but possibly hes gonna raise the turn with the bigger overpairs (personally I don't like that play)

sb range is huge, I felt strongly he had air

Turn a brick of hearts (7 i think)
sb checks, hero bets, utg calls, sb folds, now i'm confused!
