Alice O'Donnell
From Tardis Wiki, the free Doctor Who reference
Alice O'Donnell was the systems technician onboard the Drum, an underwater mining facility in Scotland. She was a big fan of the Doctor's work, and was thrilled when he arrived.
When commanding officer Jonathan Moran was killed, her friend Cass took charge. She led the remaining crew to the base's Faraday cage, where they would be safe from the ghost leader Prentis. (TV: Under the Lake)
