"What I don't get is how the ladies actually let Erik win immunity. If they wanted him out so bad, couldn't they have just aimed for only one person's colour in the challenge?"

I agree whole-heartedly. I was thinking the same thing. The women could have done it on purpose or claimed "by accident". And I know that they would have been allowed to do it because someone just missed someone else's balloon and Jeff commented about it. All they had to do was all take out Cirie's balloons (pardon the pun) since she was not going to be voted for. Then they could decide who to vote for - Erik or Amanda and make it look better to the jury that they were all ganging up on poor Amanda. They just did a reward challenge where people can easily gang up on someone to eliminate them, without the person being able to do something, so why not here. Actually I never did like the reward challenge where this can happen - it doesn't matter if you answer the questions correctly or not, you can be eliminated.
