Ever since the veto comp, both Dan and Memphis have assured Keesha that they will let her know if Memphis decides to keep Jerry. A little bit ago, Memphis came out of the diary room and said that he had been told not to tell her before the live show tomorrow night.
Memphis my be starting to second guess his decision, though, as Jerry is driving him crazy. Besides creating new conspiracy theories, he's been wandering the house counting things (ala Natalie), and reporting every discovery to a clearly bored Memphis. Every time he walks away, Memphis either shakes his head or giggles.
I really think this is a dumb move on his part. They're basing this entire decision on the fact that they can beat him in any endurance competition. They're probably correct, but the other two competitions are always based more on luck than skill. Especially the third part, which is always the "guess which phrase the jury member actually said" contest. Plus, I wouldn't be surprised if the endurance contest is set up in a way that gives Jerry a shot to win.
Keesha, on the other hand, has spent no time studying the house and has never been seen going over what has happened in the past two months. She also has been pretty inconsistent in the competitions, even when she has won. Yes, she did beat Jerry in a tie-breaker when she won her second HOH, but her first win was due to Libra missing the final question. Her one veto victory only happened because everybody else went over the hour limit in that "buried alive" contest. This is all without even considering the impact on jury votes.
