Trips on Flop - Turn str8 scare card

[JanelleBB7]

I hate these types of hands. I only have a total of 18 hands with villian and I suspect he must be a holdem player and not a regular to PLO, so I don't know what to make of his calling my raise on the flop. My 1st assumption is he has two pair because I hadn't been very impressed with the few hands I had seen him play, but of course it is very reasonable to assume he has a High wrap here. Please tell me what action should be taken on the turn.
