Kyle Bates met Ham Tyler at the prison camp in the last episode. Robin Maxwell was also there for a while and both knew the character that died, Isaac. It stands to reason that they knew each other since it was a small prison with not too many humans. However, Kyle reintroduced himself to both of them upon meeting them.
This is because the episode is an alternative to episode 3, which was pulled from broadcast..
When Ham pulls away in the red van, the cameraman is visible in the reflection on the side of the van.
