Villains are both fish.
On the turn I'm not sure if my call is that good, because I don't see him floating the flop in a multiway pot with a random Ax that often. But on the other hand, his line doesn't make a lot of sense with AK for example so that would only leave some 2P Ax combo's (and A2 in a lesser degree probably).
