Its reasonable to believe that villian has flush, but I think it is unlikely that he started three to the flush because he does not raise 4th or bet 5th. Therefore it is also reasonable to read his raise on 3rd as his belief that you did not have aces, and on 6th street as jacks up. The problem hero is faced with is that villian will 3 bet with both lower flush and jacks full. You need villian to have lower flush about 21% of the time to break even on capping.
