I do not see why couldnt villian have two pair and not call with them to our shove.

98s, AK, A9s, A8s all these hands could be very well playing like this. Even with set he could have been trying to slowplay on the flop and third flush card scared him, and he wants to put money on the turn before bad river will come.

This is clear raise for value for me.
