- Affably Evil: Pinkus's human form is a very likeable, down-to-earth guy. Don't let that fool you.
- Big Creepy-Crawlies
- Continuity Nod: Mulder still has his right pinkie taped from when it was broken in 'The Pine Bluff Variant.'
- Karma Houdini: Pincus and his group of monsters get away in the end and set up shop in another call centre. But there is another guy like Lambert over there who seems to know they exist.
- Monster of the Week: A very effective and smart one.
- Nothing Is Scarier: You only see the monster in brief, out-of-focus shots. This was the result of the special effects team desperately trying to cover up a disappointing costume, but it works very well.
- Stockholm Syndrome: Mulder denies having "Helsinki syndrome" or "Folie A Deux" with the now-dead hostage taker, both terms roughly equivalent to this. Of course both Lambert and Mulder and in her own time, Scully turn out to be completely right.
