22 1R+1A Top Two but the flush got there
 

Villain is unknown. No reads. My friend played this hand but doesn't really ever go on 2p2 so I figured I would at least try to learn something from the hand. How often is this ever a lower two pair? Can this ever be a bluff? Comments on flop/turn play also appreciated.
