This episode sets up a really intriguing mystery, with the disappearance of Jonah and others that is somehow linked to Jack.

It's an interesting episode of Torchwood in that it seems to borrow from the format of Doctor-lite episodes in Doctor Who such as Turn Left and Flatline. In this case, it's Jack-lite with Gwen taking centre stage.

I really like the inclusion of PC Andy in this; he works so well for this story in that he demonstrates the human side, and we see through his eyes the possibility that Gwen has been hardened by her work for Torchwood and lost her human touch. It allows Gwen to go on a journey to prove Andy wrong, and show that she cares about the everyday person just as much as she did when she joined Torchwood. But then that is also her downfall, because her

attempt to help ends tragically unappreciated by Jonah's Mum.

The story also does a really good job at constantly making us question Jack. Why he is so dead set against Gwen investigating, why he turns up at the place that the GPS Ianto gave her leads to. We think of him as a hero, but now we really start to wonder if he is the good guy we have all been led to believe.

Adrift is a highlight of Torchwood's second series for sure.
