More great episodes I didn't mention: Hitchcock & Scully, The Crime Scene, The Honeypot, and Ticking Clocks.

Return of the King was my second least favorite episode of the series. It seems like they have no clue what to do with Gina. She gets hit by a bus and comes back the next episode. She has a child with one of Boyle's cousins who literally never appeared before, and nothing else happened. She quits the 99 while being a complete jerk to Amy. Then she's an internet star who continues to ignore her friends and literally gets stabbed in the shoulder. None of this is necessarily bad (nothing on the show is even close to bad), but it's very random. I hate how she was so willing to quit.

Regardless 2 subpar episodes out of 128 is a fantastic show.
