I spoke to the person that had the Instagram video of Becca and Floyd doing the rap. Here is everything they told me.
They saw the following people at that location: Nicole/Victor, an Survivor team (confirmed when picture sent that it was Chris/Bret), Becca/Floyd, and a TAR team (confirmed when picture sent that it was Leo/Jamal)
They said that Nicole and Vic was the only team that they saw receive the clue to move on. Chris and Bret gave up and left (possibly to another task?). Becca/Floyd and Leo/Jamal were on their 3rd attempt when the person had to leave.
They said that Nicole and Vic were ahead of the rest of the teams by almost an hour.
I sent pictures of Colin/Christie and Rachel/Elisa and they confirmed that they didn't see any of them.
I included part of the convo.
