Max Tresilian

Max Tresilian was a human who joined Pilgrim and befriended Suzie Costello. He served as an unknowing Trojan Horse to be used as part of her plan to bring herself back to life if she needed to kill herself.

Biography
Once a week for two years, Suzie would reveal to Max her secret about working at Torchwood 3 and then wipe his memory with Retcon. Ingesting these large amounts of Retcon eventually drove Max insane and she re-modelled his mind around certain poems by her favourite poet, Emily Dickinson. After Suzie shot herself and had not met him in two months, Max began killing fellow "Pilgrims" and was captured in a bar by Torchwood. He was then taken to the Vaults, where Torchwood discovered their name drove him insane for about 10 seconds ,then he went back to being silent and calm.

As Suzie made her escape with unwitting accomplice Gwen Cooper, Max began manically repeating the Dickinson poem, "Because I Could Not Stop For Death"; this, coupled with a back door program Suzie installed in the Torchwood computers, put the Hub into lockdown, trapping Jack Harkness, Toshiko Sato, Owen Harper, and Ianto Jones. With phone assistance from Cardiff police, Jack and Tosh unlocked the Hub using the ISBN on Dickinson's poetry anthology. (TV: They Keep Killing Suzie) Max was not seen after this incident- it is likely Torchwood Three had him institutionalized.
