This is the last season ending cliffhanger of the X-Files. I hope they end it with a crash and not a whimper...
Will it be back next season or is this THE final episode?
It'll be back. Their contracts extend through next season nd then it'll be over. There are plans for more movies, though.
What I meant was X-Files' seasons end with a cliffhanger (Mulder's dead) that is resolved by the first episode of the next season (no, he ain't). This is the last time this setup will occur.
