QQ 3Bet C-Called by UTG Limper, K High Mono Flop

Villain is 26/4/1.3 over 70 hands. The original raiser pre-flop is a decent tag reg for what it is worth. I’m not sure what to read into his cold-call of the three bet pre-flop, usually that is pretty strong, but going by his stats I’m not so sure. I’m assuming the flop call is pretty standard once he does this small donk bet, although it is indicative of weakness I don’t really see what a raise achieves? As played do you fire the turn or are we just trying to show it down as cheap as possible? If so, what size?
