I was actually happy they lost the challenge after booting Vince.
It was a pretty contentious episode all around, with Nina latest hissy fit, Mike working too hard and then getting a lot of nasty backlash from Rodney and Lindsey and Shirin's somewhat odd behavior. We were getting so much conflict and so much strategy talk with Tyler talking about booting Shirin instead of Joaquin and Lindsey talking about booting Mike that I was convinced the the tribes were getting switched in the next episode, but the previews fairly clearly show the tribes competing just as they are so I guess I was wrong about the swap coming up.
Instead we have an injury, 'she's bleeding' and I believe a call for medical to come in.
