Drax surprises the Doctor with old name

The Doctor reactivates a distress beacon inside his cell, the same device that lured K9 into a transmat trap. Before he can investigate further, a hidden section of the wall opens and a rough-hewn Gallifreyan rips through—Drax, an old classmate from the Doctor’s unresolved past. Though the Doctor initially resists the familiar but long-abandoned name Theta Sigma, Drax’s blunt nostalgia forces him to confront a buried identity just as the Shadow’s relentless hunt for the Key to Time tightens its grip. The reunion is neither warm nor private, layering old rivalry with fresh danger in a confrontation that reveals as much about the Doctor’s forgotten roots as it does about Drax’s ingenuity in surviving incarceration. key_dialogue: [ DRAX: Hello, Theet.
