Back to back hands: Second hand is AA against same villian

[Hellmouth]

No read on villian less then 25 hands total. I won this first one without a showdown.

Final Pot: $10.25

So on my next hand I get AA. The flop min raise seemed frustrated so what do you think of the push? Am I only getting called here by a better hand? I thought if he was frustrated enough I might get a call from a worse hand.
