BB6 and especially Janelle has been a target since day 1 and that has never changed. If BB6 hadn't won HoH for the last 4 weeks, the others in the house would have rallied and voted out someone from BB6 and Janelle most likely was the 1st one to go. The more BB6 can cut down the floaters' numbers the better chance of survival if one of them takes HoH.Also, after all weeks' nominations, Janelle was blamed and the 2 on the block would make a pact that whoever remains in the house would go after Janelle. So, Janelle's target has never changed, it's just that certain people are being more vocal about it.
Marcellas has been a drama queen since the beginning. While getting close to Janelle, he has been running to the other floaters with his tales. That has never changed. He freaks out and it takes a few days to calm down. Remember how mad he was that Danielle wasn't voted out in week 1? Marcellas so far is all talk and no substance. He better watch himself, because he's a target too and without Janelle trying to keep him protected, he'll be gone very soon.
I still think James, no matter how much he whines, knows it's too early to jump from BB6. His only "true" ally seems to be Danielle at this time. James is trying to grow the seeds he planted with everyone else in the house, but people know his game and he's not really fooling anyone.
After tonight it will be 4 - 4 - 2 among the groups with little side alliances. The floaters also know that BB6 are strong in the competitions and the only one I could see with the real balls to try to go after BB6 right now would be Danielle. Erika and Marci would be too afraid to go against BB6 and will target CT. CG who knows, but I think he too will take the easy route and go after CT.
What Janelle is doing is great, because she is making Will & Boogie think she is taking their deal, while making them believe they are the ones manipulating her, while in the end it is to BB6's advantage to thin out another floater instead of worrying about CT. Maybe I'm giving her too much credit and she has no idea she is doing this, but taking out Diane is a really the best move for BB6 and making CT believe they are part of it is ingenious.
