Mersey girl. You could be right. Although I think BB didnt know about Kittens court appearance untill the middle of the week.
However, if they do evict just Kitten tonight, they will need to find a replacement, because the original plan was not really evict anyone until next week.(and have two fake evictions tonight, the two going to the secret room).
So The options BB have are
1) Just evict Kitten tonight and put in a stand-bye. boring option.
2) Do the original plan, have the HM's choose someone for eviction, then announce another eviction because of Kittens rule breaking, and then put the two into the secret room. If they need to evict kitten before next wednesday, then they can simply ask her to leave because of the court case.
However, if Kittens fine is paid, does she still have to appear in court to be discharged?.
