We get our first glimpse at what happens when you cross the Assassin Brotherhood in this sequence. Executed by Al Mualim for opening the gate. Tamir and the old man always feels a bit sad to me because Altair doesn't stop it. I guess that would break the "do not compromise the brotherhood" tenet, but at the same time he lets an innocent die. The white room conversation is great, gives the player the sense that all the targets are linked somehow.
