Bernie: (to Owen after wearing down from being chased) Don't hurt me, I've got asthma!
Owen: I'm not gonna hurt you. I'm gonna bloody kill you!!We join our team In Medias Res as they chase down a fleeing suspect. Tosh is certain the miscreant is the source of the alien reading they're receiving. Unfortunately, Gwen only gets so far as retrieving his hoodie. Fortunately, there's an object in his pocket which is in fact the source of the alien reading. Gwen finds the device and activates it. Through the device, she sees a vision of a young boy dressed in period clothes wandering through the train station.From the train tag Gwen saw on the boy, Torchwood is able to track him down to his current status: as an old gentleman living in Cardiff. He was left alone after having been evacuated from London when he was just a boy during World War II. Turns out the alien device is a "quantum transducer", a device that allows the user to see events spurred by strong emotion. The scene Gwen saw was brought on by the immense fear he felt at being alone.Deciding the device is dangerous, Torchwood sets out finding the original suspect they were chasing to learn where he got it. Returning to the scene, this time Owen uses the device and sees a vision of the 1960s, where a young woman, Lizzie Lewis, is raped and murdered by a suitor getting a little too rough with her. Owen feels her incredible fear and despair — a bit of a shock for him, seeing as he drugged and raped a woman and her boyfriend just two episodes ago (with the aid of an alien pheromone device) — and decides to bring her murderer to justice. Despite the rest of The Team claiming that the case has gone cold and no good will come of this investigation, Owen tracks down the murderer, Ed Morgan. Understandably, Mr Morgan has no interest in discussing the incident.During this investigation, Owen finally corners their original suspect, one Sean Harris. Sean tells Owen and the rest of Torchwood that he saw the vision of Lizzie and Ed also. He says he got the device from inside a tin he stole from an old lady, which turns out to be full of benign alien stuff that fell from the Rift. He also offers Torchwood "the second half" of the device. They put the device back together and Gwen activates it, seeing herself nearly hysterical with blood covering her hands and holding a knife. Sean says that when he used that half, he saw himself die on the road outside his flat.The team puts together that Sean used the vision of Ed Morgan to blackmail him and theorisse that Sean's future death will be at the hands of Ed, paranoid and depressed. Both men are tracked down to Sean's flat. Gwen manages to disarm Ed, averting the future Sean saw, and to talk down Owen when he, still traumatised by witnessing the rape, vengefully threatens to kill Ed. But Ed, in a fit of depression, deliberately walks onto the blade Gwen's holding, fulfilling her vision. Poor Gwen is drenched in his blood, and just... stares. The device is placed in the secure archives in the Hub, where no one else can be traumatised by it anymore.
— Owen viciously confronts a petty criminal after chasing him for 2 minutes
- Being Evil Sucks:
- Tracking down Sean is difficult because none of his known associates (including his own mother!) want anything to do with such a petty criminal.
- Ever since he raped and murdered Lizzie Lewis, Ed Morgan has lived in fear. He thought everyone knew about it, judged him, and would at any time try to hurt him. He spent decades inside his home stewing in his own paranoia and tried to kill himself twice.
- Death Seeker: Ed Morgan has twice attempted suicide. The third time's the charm.
- Dreaming of Times Gone By: The first part of the transducer shows a glimpse of the past.
- Dreaming of Things to Come: The second part of the transducer shows the future.
- Dual Wielding: Gwen, during her Training Montage, holds two guns.
- The Empath: The quantum transducer can turn people into this; they feel the emotions of the ghost in question.
- False Reassurance: "I'm not gonna hurt you. I'm gonna bloody well kill you."
- Idiot Ball: Gwen may be new at this, but one would think just activating an alien device because it's blinking would be taking a severe amount of risk.
- Inherently Funny Words: Splott, a district of Cardiff Torchwood ends up visiting. It's noted that estate agents prefer "Sploh".
- Mundane Solution: Sorry, Tosh, but the answer to tracking down our targets is not a complicated database. The phone book works just fine.
- Rape as Drama: Poor Lizzie is raped and killed beneath a bridge.
- These Are Things Man Was Not Meant to Know: Naturally, Jack has some reservation over people seeing The Future.
- You Can't Fight Fate: Or can you? Sean saw himself die, but it was averted. Gwen saw herself covered in someone else's blood, holding a knife, and that certainly happened, although not the way she expected.
