Turn 3-bet or call?

I realize that I only have 2 outs and need more than 9.25 to 1 pot odds to call (more like 22 to 1). The turn raise implies that Villian most likely has an A and possibly even spiked two pair, but Villian has been very LAG and weak (over 50% VP$IP).

I feel that at least a call is justified because of Villian, but should I have three-bet the turn at this point? Or am I completely wrong altogether and folded because of the A threat?
