Transcript by SurvivorFever.net:
Announcer: Wednesday, it's a two hour Survivor event. And the white collar, blue collar and no collar tribes are turning on each other.
Lindsey <talking to Rodney>: If you were my son, I'd break your jaw and feed it to you for breakfast.
Rodney <camera confessional>: Who the hell gets a tattoo on their face?
Shirin: I learned how to kill a chicken, but I slaughtered a rabbit.
Joaquin: Oh, sociopath.
Announcer: Then, disaster strikes!
Female: Drop it!
Female: Oh!
Sierra: Kelly are you okay? She's bleeding.
Probst: Stop! Are you alright?
Announcer: And it all comes to a head...
Probst: Drop your buffs.
Announcer: ...when three tribes become two.
Sierra: My old tribe is absolutely dead to me.
Kelly really gets clocked! The Red Tribe isn't shown in the tribes can't get along part. So one story is misdirection and one is the boot story. We see Shirin in episode 5 so episode 4 boot story could be about the blue tribe. I'm thinking Lindsey's prospects don't look so good! Then someone will get screwed by the swap and will be collateral damage in episode 5. Hard to guess who.
