Hearing Barrowman's overview of the Adipose and pseudo-recap of Partners in Crime is pretty fun, it very much feels like Jack's voice both in acting and script, which really makes it a lot more fun than it could be.

Because yeah, without that, this is a pretty boring 'story'. There's not really any information you're getting here that you wouldn't from just watching the episode. If you want to learn about the adipose and be entertained, watch Partners in Crime, if you want to learn a lot of faces about the Adipose, read the wiki.
