I wonder why they're doing this... apart from the fact that they love the Rodney McKay character... Why are they doing their darndest to avoid any Sheppard backstory or development? It's fortunate for them that Joe Flanigan is such a brilliant actor and rises above the material he's been given because for a lead male, he gets next to nothing... at least this season anyway.
As a fan, I suppose I can speculate that they are keeping all that stuff for bigger and better things... but I need a few more crumbs to keep my optimism alive. A little bit more to suggest that there's something in the pipeline for the character. Unless of course they're gradually leading Rodney into darkside...
