List of Torchwood episodes

"The Blood Line" is the tenth and final episode of the fourth series and the last episode of the British science fiction television series Torchwood, and was first broadcast in the United States on Starz on 9 September 2011. In 2012, creator Russell T Davies announced that the show will be on indefinite hiatus, citing personal reasons, making "The Blood Line" the default series finale.

Now aware that Jack's blood is drawn towards The Blessing, the Torchwood team uses small amounts of the blood to determine headings towards the two sites. Rex and Esther contact the CIA for assistance in infiltrating the Buenos Aires site of The Blessing, at the same time keeping Jack, Gwen, and Oswald's presence in Shanghai a secret. Director Shapiro agrees to the request and puts his team on the task, including Charlotte, who surreptitiously reports the mission to The Three Families. A detachment of the Argentinian Army under the command of Captain Federico Santos soon arrives to assist Rex and Esther, but while the group is loading up, a Three Families double agent detonates a suicide bomb, making the other soldiers Category 1 and destroying Rex and Esther's supply of Jack's blood. Rex, Esther, and Captain Santos survive unharmed, and Rex tells Santos to report that he and Esther were killed in the blast in order to better allow them to infiltrate The Blessing site.

At the CIA, Director Shapiro realizes the Three Families mole must be inside his team, and has Noah run a newly developed trace program to track any recent phone calls made using the Three Families' method of avoiding traces. Realizing she is moments from being discovered, Charlotte calmly retrieves a hidden explosive device from a side office, leaves it inside her purse in the main meeting room, and leaves. The resulting explosion 'category 1s' Shapiro and the rest of his team and lightly injures Charlotte, shielding her from any suspicion.

Jack, Gwen, and Oswald successfully infiltrate the Shanghai Blessing site and make their way to its exposed face, where they meet The Mother, Jilly Kitzinger, and several armed guards. The guards quickly stand down when Oswald reveals he is wearing an explosive vest (at Jack's suggestion). This advantage seems short-lived when a radio transmission from The Cousin at the Buenos Aires site reveals that Three Families operatives there have captured Esther and Rex, but when Oswald expresses that he didn't expect to leave Shanghai alive, the operatives temporarily stand down. After spending some time examining the face of The Blessing, deducing that it generates a morphic field linking the human race, Jack and Gwen question The Mother about the Miracle; she reveals that the Miracle was produced by introducing Jack's immortal blood to The Blessing- causing it to disperse immortality to the whole human race as a 'defence' to a perceived 'attack'-, and furthermore is simply the first part in a larger plan to assert control of the world. By stopping death and destabilizing the economy, the Families are now poised to take control of the banks, thereby influencing the world governments, eventually leading to a fascist oligarchy which can "decide who lives, how long, where, and why."
