That kind of touches on what I was going to say. It seems like they got a new (and very green) editing team because there was a lot more generic Reality Show 101 shit going on than a usual episode of Survivor.
With how they kept trying to pretend that other dude (Matt?) was five feet away from the idol swap, I'm almost convinced the exchange happened later in the game but they made it look like day 2. Like you said, there was absolutely no reason for Colton to go idol crazy before the team even introduced themselves. I know they only have one set of clothes, but it really looked like his outfit (or at least the setting) changed at the end of the transaction.
The funniest part of the episode was in the beginning and I hope my brain didn't just make it up. Jeff says like "You have 60 seconds to strip... everything from the truck," but I swear before he could get the second half of the sentence out, one of the girls starting taking her clothes off. Thought that summed up the ridiculous girl team pretty well.
