Jim (Lost Property)

Jim owned a business in London where the Doctor stored alien tech for safekeeping. He and his brother, Midge, who had his own shop nearby on Baker Street, were involved with multiple incarnations of the Doctor.

Jim had dealings with the Eighth Doctor and Liv Chenka during an adventure involving a Doomsday Clock.

A month after being stranded in 2020, Liv thought to remind the Doctor to visit him. Jim was upset the Doctor took so long. He suggested that the Doctor should have left the key to 107 Baker Street with him, rather than entrusting the property to Thomas Brewster.

He showed the Doctor one part of the Pandora Bolt, resembling a puzzle box. He suggested a visit to his brother, Midge, who had the other part in his own shop on Baker Street, though the Doctor did not listen.

Jim was also involved with the Curator, who dropped in after the Eighth Doctor's visit to inquire what he had taken out from the inventory.

Midge later said that Jim was confused when he gave the item to the Doctor, as they had both been given instructions by the Twelfth Doctor to keep the items a distance of 1 mile apart. When the Doctor left, Midge explained to the Curator that this happened due to misfiled paperwork. (AUDIO: Lost Property)
