When the nominations were announced, the odds for Pamela or Darryn getting evicted were extremely close - roughly "evens" each, with Darryn a slight favourite to go with one bookie out of three.
Darryn's odds started to drift yesterday, but have really risen this evening. He's 6/1 with one bookie (and as I write this, 13/2 on Betfair), while most have Pamela at around 1/10 (i,e. you need to bet ÂĢ10 to win ÂĢ1).
Why the sudden change? Well, there has been the inevitable suggestion of "insider knowledge" over on DS...
