Aces in the big blind Stars 100/200 vs Lagerborg

[Paluka]

6 handed 100/200 game.
Lagerborg raises in cutoff, Donald from Oslo 3 bets on button. I cap with black aces from the big blind, both call.

Flop Qh6dKd

I bet, Lagerborg raises, Donald calls 2 cold, I 3 bet, both call.

Turn Qd

Who wants to do what? I checked, Lag bet, Donald folded. Call or fold? Raising seems pointless.
