AA, possibly boring. $18K guaranteed

I haven't been too impressed with main villain. Too loose for my tastes but I can't remember if he got too out of line postflop.

I limped hoping the short-stack in MP would push all in. He was just recently shortstacked and I thought he would be making a play here more often than not. I'd like a better line here if all possible given my limp...
