Just how bad was my call?

[OneStuckFish]

About midway thru a 10+1 sit and go:
The player immediatly to my left who had been raising the blinds almost every single time its folded to him, then folds when I reraise him, makes a small raise 2x the big blind from one off the button. Holding A-Qs I reraise to 6x. Both of use about average in chips. He calls, and the flop comes A-X-X. He leads out for 2x the big blind..?? I reraise again to 6x and he moves in. Here my thoughts are 1.) He raised one off the button very weakly. 2.) He called my preflop reraise b/c Ive been pounding on him when he steals fairly hard. 3.) He bet with middle ace or at best my A-Q down thru A-10. 4.) Him being tired of my reraises decides to make a stand. With all this in my head, I call fairly quickly, b/c I know only one hand beats me that I feel he could have A-K..and it wasnt played like A-K to me. Turns out he has A-K. I do get lucky and spike a Q on the turn, but still wonder..how bad was my play. Did it look like a bigger ace to everyone else?
