Moot Smoth's last episode saw the first appearance of Piano Capaldi as the Twelfth Doctor (other than his deathstare cameo in The Day of the Doctor). It also features Jenna Coleman as Pancakes plus several enemies of the Doctor, including the Cybermen, Silence, Daleks and Weeping Angels. This episode was notable for confusing the fuck out of family members who are less into the show than you are.
