We review ‘Extremis’ in episode 49 of Discussing Who. Who is in the vault? What impact will the Doctor’s blindness make on how he interacts with others? Were the sonic shades cool, after all? Plus, will Clarence finally Say. Something. Nice? All this plus a brief recap of an interesting weekend at Southern Geek Fest 2. Hosted by Kyle Jones, Clarence Brown, and Lee Shackleford.
