First Post this board (hand question)

First hand Im in the Big Blind with AQ suited and its capped by the time it gets to me.
I here alot of people saying you have odds to call with anything here, but with it being capped to me, i have to figure both my Ace is beat by AK atleast , and someone probably has a over pair better than my queens? right. So did i make a correct lay down?

now i say this because at the time it was a no brainer to me.
but the baord came AA2 turn 2 river Q
and it was capped the whole, and im thinking someone has Quad 2s or cant get off KK. the 2 of the 4 that stayed the whole way showed TT & JJ

later i realized the guy that capped raised on the button with anything everytime he was on the button, the others proved just how bad they were a couple hands later, but other than flopping what would be the nuts, i still dont feel i made a mistake. does anybody agree?
