I did mean Sam Bosco - just couldn't remember his name. What I hate about them dropping the RJ s/l is that it was so prevalant in season 1 then handed over the Bosco in season 2 to only have that end in about 4 episodes (maybe less?).
What bothers me about the RJ/Bosco thing was that he planted the listening device in the office and nothing ever came of it. Most likely as this season starts wrapping up they'll bring RJ back to the forefront, they'll miss him by a hair again to go into season 3 as if he didn't exist.
I think PWS confuses Lisbon with Beckett from Castle sometimes- I know she's done it before, so that must be what she's referring to.
