Continuity: When Tina is in the foster home the camera looks through the windows at her, but when Mulder and Scully enter, the curtains are closed.

Continuity: We see Cindy and Teena at the table talking with Eve 7, drinking out of paper cups. Later on, when Mulder picks up a cup from the table, it's made of glass.

Continuity: When Dr. Kendrick/Eve is talking to the two little girls and she's clearing up the mess on the table, the position of the straw changes between shots.

Continuity: When Scully is reading report from Simmons' death, we can see that is has occured on the 7th of November, 1993; which means that whole episode takes place at the very beginning of November, but at the same time Scully and Mulder should be at Alaska (see episode "Ice").
