Looks to be IC2.
5 players participating for each tribe...
In the first cap I can make out Will, Joe, Hali, Jenn and Vince diving for the No Collars.
In these blow-ups, I see (and I'll need some help with this)...
For Blue Collar: Mike, Sierra, Lindsey, Rodney and Kelly diving.
For White Collar: Max, Carolyn and So, with someone else diving.
For purposes of fore-thought, we know that Red wins the Ep1 IC, so Nina is likely the sit-out in Ep2 IC, for No Collar.
This means that 1 of Dan (for Blue Collar), Tyler, Joaquin or Shirin (for White Collar) is in danger of being the first boot.
