This episode sets its plot up in such a way that you essentially know how it is most likely to end, but it's one of those "it's about the journey, not the destination" type situations.
This episode involves character development and wrapping up (a) plot point(s) without otherwise advancing too much. Take that as you will, but this is also a sitcom, and the jokes were *on point* in this episode. Every character was nailing it, and I found myself laughing more than I remember doing so in the past few episodes.
Hitchcock knocked it out of the park this episode. Essentially every scene with him was golden. Peralta and Boyle had their usual chemistry, and there was great use of that precedent to make some especially funny moments.
The real crown goes to a personal underdog, an actor who didn't impress me until season 3, who reached some sort of psychopathic pinnacle of humor by being both the best and worst person this episode (once you see/if you've seen it, that statement will resonate on a deeper, more meaningful level). The timing, the antics, the... the everything. Every single scene. I said Hitchcock was golden? This actor is... I dunno, platinum?
Lots of laughs, fun episode, left with a good feeling.
