Is there a possibility that the leg they're coming fresh from was a team swap? I could see Rachel/Elissa and one of Britney/Janelle and Leo/Jamal swapping with each other and then finishing in the lead. Then some combos of Tyler/Korey, Victor/Nicole, Becca/Floyd, and Colin/Christie. Then Bret/Chris could've been paired up with the spare and got whoever got eliminated? Just a theory. It just seems to line up based on who we've seen getting along so far.
And based on that theory, it seems more likely to me that Rachelissa would swap with Britnelle than Leo/Jamal, implying Leo/Jamal left. But that may be wishful thinking. The "physical leg" does seem to imply the opposite in that Leo/Jamal would beat out Britnelle, but I also struggle a little with Rachel/Elissa finishing at the very top of a highly physical leg.
