Unless you had a read that he was super passive you absolutely should call down. He might have decided to pump it up with A [img]/images/graemlins/diamond.gif[/img]x [img]/images/graemlins/diamond.gif[/img] after picking up the flush draw, and if he just outdrew you with A2, you have plenty of outs to take the lead again on the river (one of which hit, of course).
