Final Pot: 12.25 BB

No reads on villains. Is this a call here? It seems that given Button's preflop and flop actions, he is on over-cards . So all we have to really worry about here is UTG. He has played this hand very weakly so is calling while getting 12-1 worth it the times that UTG has ace-high or pair 2s? Is my reasoning okay?
