Anderson, spoke to TV Insider today and reminded the outlet that she’s “said from the beginning this is it for me. I was a bit surprised by people’s [shocked] reaction to my announcement…because my understanding was that this was a single season.”

The shaky 10th season ended with a biological threat to humanity, and Mulder at the brink of death. While tackling all that (and a UFO), The X-Files will also welcome back Monica Reyes (Annabeth Gish), one of the Lone Gunmen, and Mulder’s half-brother Jeffrey Spender (Chris Owens). Season 11 premieres Wednesday, January 3 on Fox.
