50NL Overs + FD facing raise and coldcall

UTG is megastation, 76/0/0.4 over 40 hands. Button is 48/2/2.5 over same sample. Earlier UTG called 3 barrels with A3 on a 663TQ board (other guy had A high). About 5 hands prior to the one below he gave a bunch back calling a shorties PF shove with A6. Haven't seen button show down a hand yet, he's taken a few off me IP by betting when i've checked to him. His buyin amount might be his whole roll, FWIW. Not seen him raise a flop before.

Who does what and why? If u call, plan on a low heart turn? Or a Q? Blank?
