Ok, just watched tonight's new season episode, lol...And I want to revise my original answers to your comment....
I thought you were referring to the one night that they drunkenly hooked up.
However, at the very end of tonight's episode, they were all having Christmas dinner and Carl said that it's the first time he's eating there as a member of the family, and Vine replied, "you've been dating Victoria for 4 months...." I was like, okay I'm not up to that yet in the reruns..now l see what you meant. It's awesome that they are a couple now.
