Are you sure that was Victoria + Derrick, and not Christine + Cody? The reason I ask is Christine has been rubbing on Cody an awful lot on the feeds and she rubbed through his hair too, which I personally saw. In fact, just last night Christine was rubbing on Cody again. She is married.
I havent personally seen Victoria get close like that with Derrick but I could have missed it. He does talk to her a lot and gives game advice.
