AsJs flush draw stay in or drop out?

[Hotchile]

The poster mentioned that the game was usually quite stable and that most players played reasonably well post-flop. Given the action that occurred, is it possible that AJ could have won the pot along the road? How about a limp-raise pre-flop with that many callers and then a flop checkraise? I don't know how the KQ would respond to this type of pressure nor do I know what the counterfeited 2 pair does at the river. I suspect he would call based on the size of the pot but would the extra 2 small bets have given AJs a chance to win this pot?
