p.s. Kaj the random footsoldiers are called "Soldat", they're the basic Quincy troopers, and I think the gunfighter guy that took Shunsui's eye is the general of them, or at least he was in charge of them for that attack.
Hmm, I just had a thought... Wouldn't it make more sense for the Arrancar that was pointing their blade at Urahara to be Neliel, back in her adult form? We know she was with Orihime and Chad while Ichigo was fighting Opie. Shortly after a "mysterious stranger" cuts Opie in half and we only see their blade. At a later point, we see Urahara, Chad, Orihime and hear a mysterious other person...
Am I the only one that thinks it's Nel?
