[NL2] Surprised

A new year, and I've decided to give cash game another try, but as I don't have as much time as I'm supposed to put into this, I've decided to start from the bottom at NL2, and just play for some fun

I would like to hear opinions on this hand:

Questions:
1. Am I in my full right to be surprised when I see Villian turn over AA? I would have 4-bettet, even sitting with KK
2. I was hoping for him to have JJ or TT, and just crossed my fingers that he haven't hit a set. Can I lay this down, or just call him all the way?
