It would be very un-2+2-like, but I couldn't cap the flop and I check and call the turn and river because I see her as only having one of the following: AA, KK, QQ, TT. I'd say KK and QQ are equally likely and TT is maybe half as likely. AA (obviously, is the most unlikely of all).

But, if I took your line, her flat call on the turn scares the Bejeezus out of me. She wants you to flush or do something stupid (like bet on the river with AA).
I'm pretty sure she has you beat from the flop and it just got better on the turn. And then, your only hope (that she has KK) evaporates on the river. Check/Fold or check/call if you really think she might have the other AA. I'm pretty sure you'll be looking at Queens full.
