I think he has AQ. I'd fold here.

Well...we made a test bet and he reraises when the flush hits...not very typical unless he wants you gone...I don't think so...he thinks his hand might be best but he wants a free showdown unless he improves further.

KJ/QT/JJ?

And of course it could always be a wacky way to play an Ax suited flush draw.
