If one of the twins wins veto, I think they will take thier sister off. In that case, Nak will put up Drew I think. She promised not to put up CB. She won't take a chance of putting up Karen. Putting up Marvin is a bit redundant and she went on a rampage last week of how it wasn't fair putting him up three weeks in a row. She won't put up Diane, for one thing, she needs her vote.
And for some bizarre reason known only to Diane, she is actually trying to convince Nak to put up Drew. I have to say, I thought Holly and Jase was the weirdest BB relationship so far, but Drew and Diane have won that honor. Wake up and smell the PB&J Drew, your honey is selling you down the river!
