Low pair in tiny pot 3 way

[sharpie]

SB is a ~86/20 habitual gaybettor. Interestingly I haven't seen him bluff raise or even raise much. UTG is a ~60/0/1, he'd peel the turn with any weak draw, I think he peeled the turn with undercards no draw HU on an A high board against the pf-r, although I'm assuming he needs at least a gutshot here but who knows.
