Colin Marshall
From Tardis Wiki, the free Doctor Who reference
Colin Marshall was a version of Marshall created from Leela's memories.
He appeared when Leela was plugged into the simulated world of the computer Sisyphus. He and Leela were married with two children, Robbie and Becky, who were used to try to get Leela to accept this false reality and let go of her real memories. When Leela and Jennifer attempted to destroy Crowmarsh, Marshall appeared before her and unsuccessfully attempted to convince Leela to accept the false reality, as Leela set fire to the Crowmarsh installation's gas mains, which destroyed the building and forced her to wake up.
