I don't want to say anything too specific here, either, but I know what prop you're talking about. But since the reporters were there to see filming of the season finale, I thought that the prop had to do with either ep. 21 or 22. Especially since we all thought JDM would be in ep. 20. Now, of course it makes perfect sense. :-(

Oh, don't say anything about John's fate! I'll wait for the episode for that, as sad as I'll be that he's no longer in it.
