Forum:Help fixing categories

I have been trying to organize the pages for the members of the Crusade, such as Ort, Teo, Reeden, Katz, Pyle, etc... under Allen Schezar's crew. In doing so, I discovered one of the pages not linked properly, and there are two articles on one character: Riden Garusan, and Reeden. As both are the same character, at first I became confused that the first one had my additions deleted, only to discover that there were two pages, and my first was intact.

I have added the category Crusade Members to Reeden, but cannot figure out how to remove it from Riden Garusan or delete the page. I am also uncertain whether it would be proper to do so, so any help on what to do would be great. :(

I'm sorry for any trouble! I just want to help make this wiki as comprehensive (and accurate to official titles) as possible!
