Nichols (Visiting Hours)
From Tardis Wiki, the free Doctor Who reference
Nichols was one of the porters at the hospital Brenda Williams was at. He worked out that someone had worked out was going on when Rhys Williams switched his mothers rooms. He was tasked with taking organs from live donors which would kill her. He was doing this out of blackmail to get a heart for his daughter. He was killed by the Cleaners. (AUDIO: Visiting Hours)
