Oh, Sam, this is brilliant. Nicholas fits in perfectly, I love the way you have life just go on (stumbling and limping at first, but still, just going on in an ordinary and imperfect way), Jack and Ianto's interactions, the glimpses of what happens in the field, and the way you balance funny and touching. I think my favourite thing about it is the dialogue. You've managed to get the voice of every single character, from PC Andy to Jack to John Hart, spot on. I could hear and see them clearly - it was like watching telly in my head! And I jump on the bandwagon to say that I, too, was expecting Nicholas/Hart. Though now that you've said he's shy, I'm content to imagine what might have happened off-camera. :)
