John is back with Monica and Jacque from "Girls Interrupting" to take on the leaky zombies in the David Tennant special: "The Waters of Mars"! They discuss how frightening the Doctor is in this episode, and talk about how important it is that The Doctor does not travel alone! They have a fantastic discussion about regeneration, and what it means going from Doctor to Doctor! Our hosts also discuss who they would like to see take over as show runner if/when Stephen Moffat leaves the show. So follow us through the time vortex, and take a listen!
