Mr Bird moved into the attic room of 107 Baker Street in 2020 and effectively became the other residents' live-in handyman.

He placed extraterrestrial technology in the house for the purpose of surveillance, earning him the suspicion of both the Eighth Doctor and Tania Bell, with the latter informing Torchwood that he could be a concern. He blew up the MedTech building and used vortex transference to escape before the Doctor could catch him. (AUDIO: Must-See TV)

The Doctor initially believed that Mr Bird had killed Mr Crousseau due to the presence of scorch marks, but Teeja and Bourakai admitted to being behind it. (AUDIO: Divine Intervention)
