Janie and Kaysar aren't blaming James for anything, they have just been stating their false sense of security that James intends to go after CT next.Remember, from the beginning the plan was to take out the floaters, who are considered more dangerous and have the higher numbers in the house than CT. Right now, Kaysar & Janie believe CT are easy to read and they are not worried about CT. Also, as Janie has stated she is not doing the dirty work for the floaters of eliminating the only other targets in the house.
I actually think it's smart to thin out the floaters, because if one would have won HoH, they had the biggest numbers in the house to take out whoever they wanted. After tomorrow they will be down to 4, which is a much more level playing field.
Janie/Kaysar & Howie should feel confident they did the right thing, because why else would Marci, James & Danielle be so ticked off to see Diane go unless they were mad that they were losing part of their numbers. Janelle messed up a grand scheme, which was the best thing to do (just too bad she didn't take out the queen instead of a pawn). Oh well, you can't have them all.
