“Blood”
“Sleepless”

Two good episodes of The X-Files followed one of the best one.
Both were dealing with victims who were seeing things, whether it was because of a pesticide being secretly sprayed on a small town or because of a secret sleep experiment to create soldiers who never slept.
We meet a couple of important characters to the X-Files mythology. First, there was a meeting between Mulder and his new ‘friend’ inside the FBI, X. We get to see what X looks like, though we know very little about him. And as we saw at the end of the second episode, Cigarette Smoking Man does not know who X is at this point either.

The second character is FBI Agent Alex Krycek. He is introduced as another agent who partnered up with Mulder and said that he wanted to believe. He is shown as a potential new ally, but we learn that he is one of CSM’s flunkies.
The Lone Gunmen make their return in Blood, to spew some of their paranoid ideas. They are in a short moment but they were memorable.
