Exactly. Devan needs to tell his mom about Byanca’s cheating. Her cheating in the past, the recent cheating caught on video. Then he needs to tell about Anna and Dave. Unless he is only waiting for Anna’s divorce from Brian to be done.
Why doesn’t he cancel the wedding. Tell his mom to go home.
Better yet why doesn’t one of his hired hands show him the video clip of Byanca screwing her boy toy in Devan’s house when he’s not there.
