Thomas Sutcliffe was an old friend of Rupert Giles during his Ripper years. He was part of the group which also included Ethan Rayne, Philip Henry, Deirdre Page and Randall.

By late 1997, Thomas had been killed by the demon Eyghon, who in 1975 had taken permanent possession of Randall and, after a failed exorcism that killed Randall, swore to kill those who had toyed with him. Thomas was the first of the crowd to fall to Eyghon's revenge.
