Jetsam ( comic story ) Summary . A cargo ship outside of Cardiff Bay has several alien artefacts in its hold which the crew were paid handsomely for transporting . When they first set off , the devices were dormant . However , when they got in range of the the Rift one of the devices began to communicate to the crew using telepathy . It foretold tales of war and gave the taste of blood and metal . Spooked , the crew jettisoned the crates into the sea . The next morning , the crates have washed up on a beach and Torchwood are among the first on the scene . They immediately start trying to quarantine the items and usher the public away . Tosh finds a giant motorcycle by one of the crates . In the sand next to it , however , are similarly sized tyre tracks , indicating it was part of a pair . Surrounding the large tyre tracks are several smaller motorcycle tracks . Gwen deduce s that a group of Harley - Davidson motorcycles dragged the larger bike away and that it was probably the work of a motorcycle gang . Jack orders Toshiko to start examining the remaining bike to try and find out what they are up against , while he and Gwen investigate dive bars . After investigating several , they find a bar that was virtually destroyed and smoking . Upon getting closer , they find the bodies of all the members of the Brimstone Skulls apart from one , the leader , Drew Blayney . Suddenly , they hear a revving and the stolen motorcycle , piloted by Drew , bursts from the debris of the bar and drives off , feeling no effect from the EMP gun Jack fires at it . Jack and Gwen chase the bike back towards the city in the Torchwood ' s SUV . Meanwhile , while investigating the other bike , Tosh discovers the bike operates on neural input . Suddenly , the input cables attach themselves to her and she becomes possessed by the bike . The bike smashes through the wall and onto the streets of Cardiff . Tosh retains enough of her humanity to tell Owen and Ianto that the machine is drugging her and that it is automatically tracking down the other bike . Owen manages to download information directly from the bike and runs it through a translation device . It tells him that an " unpronounceable alien race " uses the bikes for duels to settle turf wars and border disputes . The bike would do most of the work with the occupant to provide tactics . Jack orders the authority to close a section of the motorway and orders to Tosh to lure the other bike onto it . Ianto hires a helicopter for Jack so they can chase the bikes . Right by the Sunbry bypass , Jack shoots the EMP gun at Drew ' s bike and during the brief time the weapon was effective , the bike crashes . Meanwhile , Owen encourages Tosh to find mushin , a state of mental calmness that would have been featured in Tosh ' s childhood stories . When she finds it , she calms down and gets her own mind back . However , she still follows Drew and proceeds to start a self - destruct countdown , the resulting explosion from which would kill them both . Just before the countdown reaches zero , Drew ' s personality overpowers that of the bike and claims that he doesn ' t want to die . The bike takes this as a surrender and Tosh is proclaimed the winner . As Toshiko gets out of the bike , Drew sneaks up behind her with a knife . However , he is suddenly vapourised by one of the bikes for breaking the terms of the surrenders . Tosh then orders both of the bikes to shut down and delete their core programming , putting them out of action for good . References . " to be added "
