|Well, what a great episode! This is why I watch Torchwood!
Ianto calls a Japanese cybernetics expert named Dr Tamazaki to the Torchwood base after the team leaves. He's been keeping his half Cyberupgraded Torchwood 1 girlfriend Lisa downstairs plugged into cybernetic machines for months and has been looking for someone who can reverse the process and make her human again.
The Dr Tamazaki manages to remove her from her dependence on the respiratory systems so that she can function independently. Unfortunately there is a UFO sighting and the Torchwood team returns, meaning that Ianto has to leave Lisa with the cybernetics expert.
Unfortunately Lisa's cyberman programming kicks in and she tries to convert the cyberexpert into a cyberman. It doesn't work and Ianto comes back to discover Dr Tamazaki's ripped and bloodied half cybernised corpse on the ground.
Ianto is a very emotional person and he just can't deal with this situation at all. Stumbling about and trying to make himself believe that she didn't mean to do it, he hides the body.
Unfortunately the team finds that there is a huge power drain coming from downstairs and they go and investigate. CyberLisa attacks them and forces Gwen into the cyberconverting unit.
Jack gets there in the nick of time and helps Gwen out of the machine but Lisa starts stalking the group through the Torchwood building. Jack leads them away but Ianto is determined that he will save Lisa and doesn't listen to them. CyberLisa throws Ianto against the wall. He collapses, presumed dead.
Jack uses his regenerative powers to distract Lisa by absorbing two of her Electricyber Bolts, dieing twice.
Gwen and Owen get stuck in one of the morgue cupboards with Gwen on top. With fear giving way they end up snogging for a couple of minutes until Gwen's phone goes off, bringing the Cyberwoman directly to them. This is interweaved with scenes of Jack giving Ianto mouth-to-mouth and reviving him.
Toshiko manages to escape the electricity shutdown while Jack throws Pterosaur attractant all over Lisa. Lisa is attacked by the Pteranodon Pteradactyl giving them time to escape.
They take the express lift to the surface. Unfortunately Toshiko has activated the reverse shutdown protocols allowing a pizza delivery girl to enter.
When the team go back in they don't find Lisa, they find that Lisa has transplanted her brain into the Pizza delivery girl's head.
A lot of things happened in this episode and there's still more to go! So, I won't spoilt the last few minutes.
In the basement of the Torchwood building, Ianto Jones hides a terrible secret, as the sci-fi thriller created by award-winning writer Russell T Davies continues.
As a Japanese doctor attempts to rescue the soul of a half-Cybernised woman, a quiet day in Torchwood quickly becomes a living nightmare. Has Ianto unleashed a force that will destroy his colleagues?
Ianto is played by Gareth David-Lloyd
