i wouldnt be too afraid of BB. Id put him on a weak-mediocre ace, KQ,KJ,KT,KdX. But notice how UTG just flat calls on the flop and turn? What hands would he raise with UTG and with that flop just call 2 times with 3 ppl in the hand. AK,AQ,AA,KK,QQ got you beat. He might call with TT/JJ hoping to fill up/make the strait.
You probably could make an argument for everything, but honestly you have no idea where your really at without reads. Id probably make a crying call and fold to a big bet by UTG on the river.
