Spoilers!
Jack's back. The man knows how to make an entrance. And what an episode. After such episodes as Cyberwoman, I began to fear any episode that had Chris Chibnall's as writer. But I forgive him, because 2x01 rocked. Exciting, funny, well paced. And the old woman crossing the road: Bloody Torchwood. Har!
And the trailers at the end - what was that woman on her head vomiting! Looks like she had Jack trapped? *frets* Can't wait to see what happens there. Let's hope the rest of S2 is as good.
