It looks like the 4 last contestants are fighting consecutively at the same time. I previously thought Rider was the first to go in this episode. Now its pretty much set that Archer vs. Rider and Saber vs. Berserker in the last few.
I like the homo moments between Waver & Rider. Its sort of like a death flag, when he spent all his commands. Reminds me of Aladdin and the Gennie.
