I'm having a block trying to figure out the 2nd trip to SOL. I haven't heard anything about the garage camera picking up his car a second time so I don't think that he was wanting to put CM's body into her car. I don't really believe that he was trying to deliver her to anybody, he could have done that in a thousand places that are more remote than SOL. I think that he had to be going back to the apartment for some reason. Hmmmm....
