I was watching ep 1 last night and I started thinking about Master Yoda's line: There are always 2 sith, a master and an apprentice, no more, no less.
Well, when Darth Maul was cut in half was there another Sith immediately waiting to take his place (i.e. Count Dooku)? It just reminded me of the slayer rule for Buffy the Vampire Slayer: When one slayer dies another one is immediately created (i.e. Faith became the slayer when Buffy died).
Is anyone clear on how this process works?
