Yep, Drew and Sam have changed "bodies". I've struggled with what to do with Drew for a while and I decided that what was best for storytelling was the nuclear option. Sam wont be in the comic nearly as much as Drew will be so we wont have too many strips where there's the body and the ghost looking the same. Drew will have a lot of changes in his life coming up... he'll have to get a job and whatnot. Next week will have less to do with this half of the arc and we'll get to another deal with Jack and Lyn.
