With Strackman Lux, Other Dave, River Song, Anita and Miss Evangelista, he went to the Library to discover why more than four thousand people had vanished there leaving a message a century earlier. He was killed by the Vashta Nerada, although his consciousness survived for a brief time as a data ghost.
Afterward, the Vashta Nerada animated his skeleton and he became a Suit Creature. It continued to utter Dave's final words, "Hey, who turned out the lights?" as a data ghost which had fallen into an infinite loop. (TV: Silence in the Library) He was returned to life in the computer core after CAL and Doctor Moon had saved him and the rest of the team. (TV: Forest of the Dead)
