I was going to do an eviction odds thread, but I couldn't be bothered as it's extremely one-sided:
Jemima 1/5 favourite to go (1/8 with some bookies);
Dexter 4/1 (down to 7/1 with some bookies);
Gina 8/1 (11/1 with some bookies)
So: Jemima's hot favourite to go on Friday, with Gina most likely to be saved tonight.
Personally, I think Jemima needs a miracle, but I'm not convinced that Gina's the dead cert for saving that the betting and forums seem to assume...
