Last Torchwood season was a special of 5 episodes, entitled "Children of Earth". This is the best episode up to now, this is exactly what I was looking to see from Torchwood. Surprises and twists, and if the series continues, I expect the same quality.
The story is simple but complicated at the same time. Extraterrestrials are using the children all over the world to communicate with humans. "We are coming": nothing more nothing less. But who are they? Have they been here before? Why are they coming? What is the link between them and the children? And what does Jack have to do with all this?
Spoiler warning, for the rest of this post. So, if you haven't watched the special, and you don't want to know some details, don't read ahead.
Their name is the 4-5-6 and they have been here before. They want children, specifically 10% of the world's children population. What do they actually want with the children?
Jack, Ianto and Gwen need to know what's coming. Torchwood has been destroyed, Jack has been jailed, Gwen, Ianto and Rhys are on the run. They do find some unexpected help, but is that enough before the 'units' are shipped?
When Jack tries to stop the 4-5-6, they respond, killing everyone in the building that houses them, including Ianto. Torchwood has lost, Gwen and Rhys are taken back to Cardiff, Jack is once again jailed.
However, the people that initially tried to kill Jack, free him. He finds a way to stop the 4-5-6, but this way has a terrible price for Jack: he has to sacrifice his grandson...
The deaths of Ianto and his grandson, as well as the deaths of Owen and Toshiko, weigh heavily on Jack. He spends a few months here and there on Earth, but he can't escape his feelings. He finds Gwen and Rhys to say goodbye, and leaves Earth.
Again Davies left us with a bitterness at the end of this season of Torchwood. It is after those events in Torchwood, that the Doctor finds Jack to say goodbye, and Davies has tied the timeline quite well.
I hope to see Jack and Gwen in the future, even as guest stars in the new season of Doctor Who. Can you imagine Rhys in the TARDIS?
My information tells me that the new Doctor Who series will start March 13th. One month more or less, and more information says that River Song will return in Episode 4. Can't wait.
I want more Torchwood. I want more Doctor Who.
