I know this is a quote from hours ago and I haven't read the whole of this thread, but I'll say it again - there was the same traitors pledge last year. Keiron chose to break it.
Harry for the win! I really, really hope he makes it through. I fear he won't, but he deserves to win. It's all very well admiring Jaz for spotting Paul was a traitor but unless he pulls something out of the hat last minute he hasn't achieved much for being the smartest one in there.
