Owen goes to the nuclear facility , reminding his teammates that he ' s king of the Weevils . The others are attacked by Weevils at the Hub , but subdue them , only to be locked into cells by Gray . Owen , at the nuclear facility , tells Nira Docherty , a scientist who is trying to contain prevent a meltdown , to leave . She refuses for a few moments , claiming a soldier never leaves their post , before Owen reveals his layman ' s knowledge about the nuclear station is adequate . Although Nira thinks it sounds more dangerous outside , Owen figures it ' s about even with the situation at the plant and gives her a can of Weevil spray , sending her on her way , thanked by Nira in return . Owen waits for instruction from Toshiko , admitting to her , " Tosh , you ' re going to have to help me out here . I haven ' t got a bloody clue what I ' m doing . " Tosh tells Owen her plan to divert a secondary power source for Turnmill that will restore its power , and if it works , she can guide him into restoring the coolant system . However , while her attention is focused on using a remote control device , a gunshot rings out and Toshiko stumbles backward , before noticing a huge amount of blood oozing from her wounded stomach . She glances up to see she has been mortally shot by Gray , who stares back at her with cold hatred , before toppling over in horrific pain . Gray kicks away her device and mocks her , seeing death as more of a relief and asking her how it feels to be dying , declaring the battle to be over . A knocking interrupts his taunting and he heads for the morgue . In agony , Tosh makes her way down the steps to the autopsy room , gets her device back , and injects herself with a powerful pain - killer . She denies that she ' s hurt when Owen asks and helps him to flood the room he ' s in with coolant , halting the meltdown . As this is happening , Gray discovers Jack in a cryo - chamber in the morgue , placed there by Torchwood in 1901 on his own request . He tells Gray he forgives him . Gray refuses to give him absolution , so Jack uses chloroform to put him to sleep . He frees the others from the cells and they head back to the main area . However , an unexpected power surge alerts Tosh that there is going to be an emergency lockdown once it hits , which will seal Owen in the station . Owen sees the doors closing and makes a run for the exit , but fails to make it out in time , leaving him to face his death all over again .

When he figures out Tosh can ' t help him , he starts panicking for the rest of his teammates to come rescue him . Once he realises it ' s hopeless , he dissolves into a screaming rage . Toshiko , dying , asks Owen to calm down . He demands a reason . Tosh tearfully replies , " Because you ' re breaking my heart " , and he is quiet . The two talk as they prepare to die , Owen unaware of Tosh ' s wounds . Owen asks what will happen to him , and though Tosh resists explaining at first , Owen begs her to say it because he needs to know . Tosh replies that the room where Owen is locked inside is a containment chamber which will flood with irradiated coolant . Owen concludes his body is going to slowly decompose as he watches . Tosh regrets being unable to stop the power spike , but Owen responds there was no way she could have known about it and thanks Tosh for saving his back so many times before in the past . He remembers back when Tosh had to fill in for him on his second week at Torchwood by pretending to be a doctor when investigating a Space Pig because he had a hangover , and the two laugh wearily . Owen realises they never had their date together and apologises because they " sort , er , missed each other " , and for not noticing Tosh ' s love for him until it was too late , reciprocating it back to her . The coolant venting process activates , and Owen lets Tosh know it is starting . Tearing up , Toshiko starts to grieve for Owen , but Owen lets her know it ' s okay . Coolant pours into the room where Owen is trapped and he accepts his fate . Owen tells Tosh it will be all right . He calmly stands up and prepares to die .

" Toshiko bleeds to death as she watches the screen show Owen ' s fading signature . Jack and the others arrive . He notices the puddles of blood leading down the steps of the autopsy room and sprints to Toshiko , cradling her .

She looks in Jack ' s eyes and smiles at him one last time before her life fades and her face goes slack . Gwen and Jack cry helplessly for their deceased teammate . Ianto leans himself against an autopsy cart , trying to maintain his composure , while John looks at them all solemnly . The following morning , a news broadcast airs in Cardiff about its efforts to recover from the attacks during the previous night . Rhys holds Gwen beside him , who is filled with misery . Back at the Hub , Jack prepares to cryo - freeze Gray , though John is quick to warn him that if Jack woke him up in 100 years , he will not have grown any better from his tortured state of mind . Aware of this , John suggests killing Gray could be the release he needs . Jack refuses to entertain the thought , believing too much death has occurred . John comforts Jack by saying it wasn ' t his fault . He also questions him for not putting up a fight when he was being buried alive . He tells John it was his penance , answering his curiosity . John reverently bids farewell to Jack with a hug and kiss , then consoles him for his recent losses . Jack and Gwen gather Owen and Toshiko ' s personal belongings for archiving . When Jack collects Owen ' s lab coat adorned with colourful pin - back buttons , and Gwen bags up Tosh ' s raspberry - coloured glasses , the pain of coming to terms with their deaths resurfaces and they become tearful all over again . Meanwhile , Ianto reluctantly begins Owen and Toshiko ' s respective final logouts , soon joined by Gwen and Jack . Upon finishing Toshiko ' s , a video appears in which she thanks Jack , admits her love for Owen and hopes she didn ' t die for nothing . It evokes a few smiles from the group , despite the great sadness they feel over her death . When Toshiko ' s farewell message closes , Jack lets his grief subside and resolves that the team has to carry on .
