$22 Deep Stack -- What Hand Does This???

Sorry, too many tables to convert. No read on the Villain for the same reason. Could not think of a hand that made sense for UTG here, so I thought I was ahead enough here to call.

Blinds are 50/100. Shorty snadwiched between us in the hand has about half our stacks.
