PLO $50 - Weird top-bottom 2 pair, donked when straight card hit
 

Villain is an extremely loose and somewhat passive and straightforward postflop
54/14.3/1.80 (32). No other history or reads. My plan was to pot a blank on the turn. However, his turn play surprised me and I read the donk bet as a made straight. Any comments on my play?

no, he has a flush draw and 2 pair that would be a terrible fold...
