Okay here's my official read:
UTG has the flush, he's just bad. He called with the draw on the flop. He hits it on the turn and comes out betting (He just hits the automatic bet button). MP has the set and wants to test the waters to see if anyone has the flush. He raises the weak bet on the turn. UTG of course calls because he has the flush. On the river UTG gets "aggressive" again and autobets. MP obviously doesn't have the flush and is scared someone has it because he got two callers to his turn raise.

UTG's $2 bet on the turn and river led me to the conclusion that he is just plain bad. This convinced me that he would have chased the flush with bad odds. Why would he check the flop and bet the turn unless the 4s helped him? I'm pretty sure UTG hit the flush. Of course hero couldn't of known this at the time...I speculate after seeing all the rounds.
