Back to Reconville again, we are on the planet Mira and Doctor Who looks set to hand the Tarranium core over to Mavic Chen. But what's this? Dennis Spooner? Oh, so Terry Nation's not even writing the script anymore? Will that mean that there are different positives for host Toby Hadoke and his guest, Ian K McLachlan, to battle over?
