Richard Pritchard

Richard Pritchard was the representative of Vector Petroleum and Vice President of Sub-aquatic Resources on board the Drum, an underwater mining facility in Scotland.

When commanding officer Jonathan Moran was killed, Pritchard took charge. When the Twelfth Doctor arrived and raised awareness about a missing power container from a discovered spaceship, Pritchard made it his mission to find it.

Later, when he had come back from exploring the lake, he was met by Moran's ghost, who drowned him. Clara Oswald and Mason Bennett saw his body floating out in the water, but then were met by his ghost, which attacked them but was repelled by the light.

Later, the Doctor led the ghosts into the base's Faraday cage, trapping them with the intention of discovering what they were all muttering in unison. After the Doctor left, the ghosts figured out a way to flood the base. (TV: Under the Lake)

The Doctor told Clara that UNIT would cut out the Faraday cage and eject it into space where away from the Earth's magnetic field, the ghosts would dissipate. (TV: Before the Flood)

Behind the scenes
Pritchard's first name is not spoken on screen, nor does it appear in the credits. However, it is briefly shown on his Vector Petroleum business card roughly 11 minutes into Under the Lake.
