Frank is only there because of Boogie though if he stays. If I were a HG I wouldn't give him anything. I mean, honestly, he hasn't really been outstanding in any of the comps so far. I don't even know why he is considered the biggest threat in the house. He has potential and a good social game, but Shane is easily a bigger threat.
The DR is totally going to intervene though and probably tell the HG's that things being said about Janelle are untrue and try to sway them. I know the producers love Frank since they saved him from going home last week and did a segment with his family, but I think they love Janelle more as she brings in the viewers being the public's fave. I don't expect they're going to let her go easily nor do I believe that she won't come back in some kind of Pandora's box twist if she is actually evicted.
