From a purely neutral perspective, I would have expected Talos to be promoted to XO, and Corvin promoted to CAG.  Not only does it follow the chain of command, it also plays to their strengths.  The CAG is an administrative, leadership role, as is the XO.  Out of Talos and Corvin, Talos would be best suited for the XO position because she has experience in a similar role.  Corvin should be able to fit nicely in as the CAG, but I'd hardly expect him to take on the monumental responsibility as second-in-command of a Battlestar.<br/><br/>It'd be like asking a fighter pilot to take over an aircraft carrier in a battlegroup.  It just doesn't make much sense.<br/><br/>Also, isn't Corvin a marine?  What would a marine be doing as the XO of a<em>naval</em>vessel?
