20/180 confused 2 pair

[AllinDan]

Raise flop for info? I don't think he has a straight on turn because of his flop lead, but I'm seriously worried about 77 or 99. However I think he's playing it the same with JQ-AQ, and could also have some sort of draw on flop that made 2 pair. I was confused throughout, help please!
