Xemnas put Marluxia in charge of the castle

They wanted power as far as we can tell

He's not exactly subtle about it

Roxas

Do you mean between CoM and 3?

Iirc Diz lead him out, Castle Oblivion is in the real between so cross over is easier

Mickey describes it as they just lost track of each other-

thats basically the same question as earlier

Why especially Marluxia?

Riku Replika should wait for Sora on the 10. Floor but he showed up a floor higher.

In Com Riku Replika is attacking Sora infront of Naminé so Naminé deleted his memory and broke his heart with it but he came back to attack marluxia in the end. But how did he recover?
