I don't think Susannah can win now. Her only chance was to make an alliance with Bridget.
Not that she was being honourable in her pact with John and Jonny though - I think she has underestimated the strength of the John/Jonny alliance.
She still has a 1 in 3 chance of winning the next immunity challenge. But I think that we can safely say she's not going to win the vote in the final.
I'm totally addicted to this series and I didn't even watch the first one.

I've started watching episodes from the US series and I'll soon be getting episodes from UK Survivor 1.
Can't wait.
