Jorj

Jorj was a member of janitorial staff aboard a Mondasian Mondasian colony ship. When his crewmates travelled to the bottom of the ship, Jorj was left alone at the brig, until the arrival of "" and her companions.

Traversing into danger
Jorj was one of fifty skeleton crew members aboard a colony ship, travelling from Mondas to pick up colonists. When the ship almost traversed into a black hole, around twenty crew members were sent to the bottom of the ship to reverse the rear thrusters. They were never heard from again.

Shortly after, a group of Patients ascended from the lower decks and took the rest of the humans away. Jorj, the only non-human member of the crew, attempted to fight them but they overpowered him.

The arrival of "Doctor Who"
Two days later, Jorj discovered the arrival of Missy, Bill Potts and Nardole aboard the ship's brig. He spoke to them over a monitor from a back room and advised the group to stay where they were. Entering with a gun, Jorj asked if there the group if there were any humans present among them.

Three inertia lifts began ascending from the lower decks with "things" in them, causing Jorj to realise that one member of the group must be human. As the Twelfth Doctor came out of the TARDIS, Bill admitted that she was the human and Jorj threatened to kill her. As the Doctor tried to negotiate, the lifts arrived and Jorj shot Bill.

After Bill's body was taken away by a group of Patients, explained what had happened to Jorj's crewmates: time dilation. The Doctor used Venusian aikido to incapacitate Jorj, and he Nardole and Missy descended to the decks below. (TV: World Enough and Time)
