This Time Ram, we cover the end of David Tennants' first reign as the Doctor with 2009/2010's 'Logopolis', putting aside the emotions to focus on maths and entropy... Because RTD would do that. So join us for the tragic fate of Rawling Cranfield, New Years Eve costume ideas and Donna's new job as a rat-catcher in That London! It's more fun than a delta wave augmenter.
