This flush tastes like burning

OK, one more quick one from the other night. This happened not long after the first hand I posted and the Villain (covers) is the same player. Some limpers and I ($1200) limp with K[img]/images/graemlins/heart.gif[/img]T[img]/images/graemlins/heart.gif[/img] in the CO, button and blinds come along...

Flop: (5 players, $50) A[img]/images/graemlins/spade.gif[/img]5[img]/images/graemlins/heart.gif[/img]2[img]/images/graemlins/heart.gif[/img]
Checked to the button who bets $65, everyone calls, I call.

Turn: (5 players, $375) J[img]/images/graemlins/heart.gif[/img]
Checked to me and I bet $300. Only villain in MP calls.

River: (2 players, $975) 2[img]/images/graemlins/club.gif[/img]
Villain leads for $500, I ???

I could not come up with a good range here. One would think that an aggro player would have done something on the flop with A[img]/images/graemlins/heart.gif[/img]x[img]/images/graemlins/heart.gif[/img] or a set. Again, this looks like a value bet, but I am unclear if he is even trying to read my hand and could be value betting a weaker holding hoping the board scares me somehow.
