The airing was advertised as a special prior to it airing. And I believe some days before because we saw the promo clip in the recording for something else. It's a fluke I saw the mention because I'm normally quick about skipping over commercial breaks.

I still enjoy the show, but I wish they'd do more with the larger story arc. It's one of the things that bugged me about X-Files as well. During the first season they built up this good back story with the ZFT, "the Pattern," Massive Dynamic, etc... This season they're letting it all go to waste. And even the very few episodes that contributed to the longer arc weren't as tightly integrated with the issues/points they set up last season as they could have been.

It seems like they're catering too much to the ability to show episodes out of order for possible syndication.
