Pilgrim (organisation)
From Tardis Wiki, the free Doctor Who reference
Pilgrim was a small Cardiff-based discussion group on metaphysical and philosophical matters, run by Mark and Sarah Briscoe, to which the rogue Torchwood 3 member Suzie Costello belonged.
Susan used mind control and Retcon to program one Pilgrim member, Max, into murdering the Briscoes, Alex Arwyn and to attempt to kill another member of Pilgrim, Lucie McKenzie, and Suzie herself had died. Costello had, in fact, used the Pilgrim mystery as bait so that Torchwood 3 would bring her back to life with the resurrection gauntlet (TW: They Keep Killing Suzie).
