Three of a Kind is the second of the Lone Gunmen-centric episodes, the first being Unusual Suspects. This is a great episode, and like Unusual Suspects, stars only one of the dynamic duo, this time being Scully instead of Mulder.
It opens with Byers during a voice-over, the first and only time a Lone Gunmen does a voice-over. The Lone Gunmen show that they can carry an episode. This is probably why they eventually got their own series.
I like how they revisited the Susanne Modeski story, instead of just inventing a new storyline for them. Gillian Anderson shows in this episode that she can do some comedy herself, and she doesn't just have to play the straight-man to Mulder's comedian. She is great in her portrayal of "Bimbo Scully". This is only time you'll see Scully like this, so cherish the moment.
I found it interesting that Frohike recognized Scully's laugh, since she rarely ever laughs in the X-Files. It was cool to see Scully return the favor to Michael McKean, by giving him a butt slap, referencing back to the Dreamland episodes from earlier in the season.
I also liked some of the creative shots, particularly from inside the ice machine and from the bottom of the ice bucket.
Three of a Kind has a great mixture of humor and a serious plot dealing with Susanne Modeski and political assassination. It looks like the actors had fun doing this episode, and I had fun watching it. Three of a Kind is a sweet treat for Lone Gunmen fans.
