As season finales go this was somewhat of a disappointment. I enjoyed greatly the follow up episodes at the beginning of Season 7 but this one did a little too much setting up for that storyline and didn't really leave me feeling it absolutely necessary to see the next two. I think part of the problem may be that I never saw this episode before I watched The Sixth Extinction. So I already knew what was going to happen and the cliffhanger kind of lost its effect. What was good about this episode is we are returned to Mulder's brain cancer whatever thingy which later we find out is happening because of his exposure to the black virus which he has become immune to. Anyway not much else I could say other than 7/10.
