They should do a Roseanne thing with Claire and Chloe in the same episode. Actually, I quite like Chole's Kochanski. I think she gets a bit of stick because the show became a bit less anarchic and a bit more mainstream when she came on board but it was still hugely enjoyable. BTE was even more muted and needs a lot more zip but I don't think that the absence of Chloe would be an asset to an ongoing series any more than the absence of Kryten (who also wasn't in the original cast) would be. She does bring an additional dynamic that the writers can work with even if she has to play the 'straight man' much of the time. If anything they need to change up Rimmer and recapture more of his early general awfulness which was so funny.
