Crane was contacted by the Advocate and Lau'Tan. He was convinced to help them release the Enochai beneath Greenwich Park by a promise of a new life and power. He believed the Enochai to be angels, and, by association, the Advocate and Lau'Tan to be God's messengers. Crane researched the Doctor, gaining access to files from UNIT and Torchwood, and began to forge documents to convince the Doctor to help him.
