Jueves

Jueves was an agent of Sabbath. With Sabbath's time travel technology, he carried out missions throughout history. He was sighted in Florida, 1935, with a Mexican man with a rifle; Rome, 1980; and England, 1907. He met the Eighth Doctor in Spain in 1937. (PROSE: History 101) Sabbath's admission that Jueves went by a second name in 1937 implies that Jueves and Sasha were the same person.

Behind the scenes

 * The appearances of Jueves in Florida and Rome are references to the attempted assassinations of Franklin Delano Roosevelt and John Paul II in 1933 and 1981.
