Alexandria Castle
When you take control of Zidane it wont be long before you fight Baku (With Benero and Zenero as well this time). Take out Benero and Zenero before destroying Baku(King Leo). When you are in the sword fight with Blank, try to do what he tells you as fast as Possible.  If  you pull it off you get Gil. After The Sword fight you will rush out and beat up two guards. go to the top of the stairs and a hooded Girl will come out. Speak to her for a bit then let her pass. you then realise it`s princess garnet!
Around now you should change to Steiner, otherwise known as Rusty.
Skip through the inane chatter, it is uninportant. You must find all of the Pluto knights.
First go into the Guard room where Zidane beat up the two guards. tell the two Pluto knights what to do, then take a quick l look at the paper on the wall before saving with the moogle.
Now go talk to Queen Brhan, she will give you an Item.
Next go back down the stairs and up into the hall.
