I dump it if you haven't seen him do this before with a marginal hand (KK/QQ). His preflop range seems fairly tight here (AK/KK/QQ/AA), and given action, I assume he has AK here and dump it because not many people would follow up on the turn with KK. I think calling the flop is fine, and checking behind on turn and then vbetting a non-k river (if checked to of course) is optimal. I definitely think I find a fold here.
