TPTK, Nut Flush draw hand question

[Black Aces 518]

Playing the Stars $3R satellite to the 500K. It's just after the rebuy period. Villain hasn't been at the table that long, but was fairly wild and aggro during the rebuy period (which is not unusual or surprising, obv.) Hasn't gotten out of line (at least and had to show) since the break. Blinds are 100-200. Hero has 9900, villain has 21K.

Hero is folded to in MP3 with A [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/spade.gif[/img] and raises to 600. Villain minreraises from SB to 1000. I hate the minreraise, esp out of position, but I can't fold here, right? I tell myself to be cautious on the flop and I call.

Flop is QJ7, all clubs. Villain leads 1000. Hero?
