Which doesn't bode well for the imminent fifth series. Neither does the absence of Sheridan Smith as Joey, whose character has a wonderful rapport with Jonathan. Wiki says it'll feature Sarah Alexander as Polly, Jonathan's wife, who...well, could be good, might not. As she hardly featured in Savant... it's hard to tell. It'll certainly be a different dynamic than any that's featured before. Mind you, Wiki also suggests that Caroline Quentin has expressed interest (or "expressed unstressed," but I think I know what they mean) in returning as Maddy for a guest appearance. No, just bring her back permanently and have done with it! When I met Stuart Milligan at a Doctor Who convention a couple of years back, he said he'd happily return as Adam if they made any more - presumably he was unavailable for Savant..., but the character of Jonathan has apparently moved on from that life, so it would be difficult to shoehorn him back into it.
In other news, have spent most of today in bed sleeping off a headache. Now I should be asleep, I can't get to sleep. Rabbits and blast.
