Oh yes it's his job to do that, even if he didn't want to write a bible thing, when she submits the script he can correct it, he heavily edits the scripts, so he's being lazy and inept himself here. I'm kind of ambivalent about show bibles, unless they are just a loose set of guidelines about backstory and canon, because I've seen shows where characters with no chemistry at all have been put together, and I like how changes were made in TW when they realised some things worked well, and for example GDL stood out, so they didn't kill Ianto in the first few eps, Kai Owen worked well, so Rhys survived as well. To me it was what made the show work, ditto for not killing Ianto and going with Owen. However that's kind of different, but some of the US dramas have been that rigid with their "bible", and IMO got really dull and boring. TW went off the rails as we know, but I think that's down to RTD and his "vision" more than anything else.

It just feels like he used the idea of TW, and threw a couple of characters in, but didn't actually give a toss, he just needed a Hollywood project.
