TW #15 : Sleeper

Tosh: You said we weren't allowed to use that again.

Jack: It's just a mind probe.

Ianto: Remember what happened last time you used it?

Jack: That was different. And that species has extremely high blood pressure.

Ianto: Oh, right, their heads must explode all the time.

Episode 15:     Sleeper.
Companions:   Jack Harkness, Gwen Cooper, Toshiko Sato, Owen Harper and Ianto Jones.
Air Date:         23rd January 2008. 

A burglary turns into a slaughter and Torchwood suspect alien involvement. When the investigation escalates into a city-wide assault, Jack realizes the whole world is in danger.

Sleeper is a story about alien invasion but not the sort that we normally see. In this story we have an infiltration by aliens referred to by Jack as Cell 114. They come to Earth disguised as humans but with their true identities locked away until triggered. At which point they show certain shape-shifting qualities and try to disrupt Earth's defences. The team have found one who they help retain their human identity and try to thwart the invasion.

When this story first aired I figured that the invasion by Cell 114 was going to be the overarching plot for this season. It sets itself up perfectly for that but alas no, Sleep is simply a one off episode with no connection to anything else. The events are never referred to ever again. In hindsight this does spoil the episode for me because by itself the story doesn't do anything. You can't drop something major like this down and then just walk away in my opinion.

Sleeper isn't a great episode anyway. There is nothing to drive the main characters forward either with their own stories or the show in general. Already season two shows that it isn't going to be as good as season one. We know that as the show goes along it gets weaker and weaker each season. I do wonder whether Torchwood should have been left with just the one season?
