Granddad Prentis Hancock (Army of Ghosts)
This week, Nathan’s hiding in a sarcophagus, James is transfixed by a giant ball, Todd keeps trying to lure his workmates into the next office, and Richard just wishes Tracy-Ann Oberman would do a better job with her hair — while all around them, Cybermen are busily pressing themselves into the skin of the universe. Our flight through Series 2 is nearly at an end, so it’s time to face an entire Army of Ghosts.
