While I don't usually give credence to cast lists, the fact Jack Plotnick just showed up and isn't accompanied by Kevin Corrigan (Kirkland) gives the Partridge is RJ theories a big boost. If it was just a "recap of the suspects" kind of appearance it would also include Kirkland's character so in my opinion it indicates a new appearance by Partridge. Of course if my theory that Partridge was an RJ disciple is right then it makes sense that we'd get more story leading up to his death. Either way, obviously Partridge has something else to add to the story, could be as RJ.
