Episode 7.4
Relentlessly pursuing the Galaxy’s most feared evil gang of criminal masterminds, the Think Tank, as they traverse both time and space in what looks incongruously like rather a nice Japanese patchwork box, Alan had assumed they must have stolen a Galifreyan Type 40 TARDIS, the Morgan Roadster of its era though with a notoriously dodgy chameleon circuit. He’d assumed they must have burgled a craft fair at some point and the external appearance had got stuck. There had been some wry smiles from the Daleks early on in the Time Wars! But now he’s face to face with the evil fiends and can see the modest size of their accommodation, he’s not so sure.
