Yeah, and the whole concept of victory being a matter of semantics as to who really wins or loses in the larger scope is basically the ending of "300" also.  Well, not basically - it is.  Six-pack Faramir reminisces on King Leonidas' cryptic talk of victory and later explains to the Greek army that it is a symbol.

Love the show, great episode, and I thought the moment where Spartacus seizes the blade and tries to turn it on Crassus was epic.
