"Toshiko is given an alien pendant which enables her to hear other people's thoughts, as Russell T Davies's sci-fi thriller continues. As the rest of the Torchwood team puzzle over a centuries-old skeleton, the pendant forces Toshiko to question her commitment to Torchwood. Is her new-found ability a blessing, or a curse?"
The article also includes a rather long interview with Naoko Mori, the actress who's played the role of Doctor Toshiko Sato every since her debut in "Aliens of London" last year.
Naoko Mori is hoping to strike a blow for geeks everywhere as she stars as technical expert Toshiko Sato in Russell T Davies's dark and sexy sci-fi thriller, Torchwood. It's a commendable stance but, as the bubbly young actress freely tells Nicola Hicks, not entirely altruistic.
"I think geeks get a really bad press but I'm a bit of a geek myself," laughs Naoko (31). "I love computers and gadgetry or anything technical. I always have to have the latest thing – I'm Japanese so it's in the blood!"
It's no surprise, then, that Naoko is so fond of Toshiko, Torchwood's computer and surveillance specialist.
"It's the perfect job for Tosh," explains the actress as she takes a break from filming at the series' futuristic set in Cardiff. "She's at the cutting edge of technology and with Torchwood she's always coming across new things. She loves the challenge of trying to work things out."
More often than not, she reveals, Tosh is pitting her wits against alien artefacts that could help the team in their fight against criminals – both human and alien.
"Tosh gets her hands on lots of alien gadgets and they're brilliant," says Naoko, who covets a rather handy device that can pick any type of lock in seconds. "I'd quite like some of them in real life!"
At first glance, Tosh appears to be the straight man of the Torchwood team, who are based in the institute's headquarters, The Hub, in subterranean Cardiff.
"She seems to be a bit square and quiet but she's actually just a very private person. She's more of a thinker than a feeler but that doesn't mean she doesn't feel, she just doesn't share it," says Naoko. "She keeps her private life private and work is work. But work is the biggest thing – she loves her job, as everyone in the team does."
Brainbox Tosh was snapped up by a Government science think-tank straight from university, before being recruited by Torchwood to work with Captain Jack Harkness (John Barrowman) three years ago. Both of her parents were in the RAF, while her grandfather worked in Bletchley Park, the top-secret wartime code-cracking facility – so she's no stranger to subterfuge.
"Tosh is very professional and work-orientated and, although you don't get to see too much of her private life early on in the series, you do later on," reveals Naoko.
Torchwood's gadget girl also fits in well with the rest of the team.
"It's like a hothouse thing. They're all cooped up in The Hub but also in this secretive, underground world that they can't share with anyone else outside. So it's very intense and intimate," says Naoko.
"Tosh has good relationships with everyone, especially Jack, the leader. She's not scared of expressing her opinions with him. She's very honest – if she feels something's wrong, be it morally wrong or whatever, she'll say so. But theirs is a very strong bond."
The computer expert also has a soft spot for handsome medic Owen, played by Bleak House star Burn Gorman.
"Owen is ... well, he's gorgeous but he's a pain," laughs Naoko. "He's that guy at school who's a bit cocky. There's a healthy banter there and he's always coming up with cheeky quips but he's one of those guys you can't help but really like ... and fancy a little bit."
The actress was born in the industrial city of Nagoya, Japan. When she was four, her businessman father was transferred to the US, so the family moved to New Jersey, where Naoko and her brother and sister learnt to speak English.
Eight years later, the Moris moved to the UK, settling in Surrey, where Naoko began to take singing lessons. By the age of 13, she had left her childhood dream of becoming a golf pro at the first hole and decided her future was in singing and acting.
Naoko got her big break at the age of 17 when she landed the lead role in the West End production of Miss Saigon – opposite Torchwood's John Barrowman.
"It's so nice to work with John again and we get on really well," says the actress, who is perhaps best known to British TV audiences as Sarah, Saffy's best friend in the hit comedy Absolutely Fabulous.
Naoko, whose diverse CV also includes Spice World (the Spice Girls' movie), Mike Leigh's Topsy-Turvy and the powerful BBC docu-drama Hiroshima, got a taste for sci-fi when she appeared in the first series of Russell T Davies's new Doctor Who. She was delighted to be cast in the episode Aliens Of London – although she wasn't quite sure what to expect.
"I didn't know too much about Doctor Who. I grew up in the States, so I'd never seen it as a kid," she says. "When I got the script, I phoned my agent and said, 'What's a TARDIS? I've looked it up in the dictionary and I can't find it'. He was laughing so hard he actually put the phone down on me."
But Torchwood, Naoko points out, is an altogether darker prospect.
"It's been a real challenge and also very exciting at the same time, because Tosh goes through a heck of a lot and some very emotionally heavy scenes.
"I've always wanted to do a science-fiction thing and an action thing – they're on my list of things to do before I die – and with Torchwood I've managed to tick both boxes. There's a lot of running around with guns and there's all that sci-fi stuff, but there's also really good drama with great characters and storylines."
Naoko has also loved living in Cardiff, where she's been based since April this year.
"I'll be so sad to leave. I really like Cardiff – you've got everything you need from a city and then you have the bay and the valleys. There's a sense here that you can really relax," she says.
She'll also miss the rest of the cast when filming wraps up this autumn.
"I've done a lot of TV series and you're very lucky if you come away with one good new friend, but the first thing I noticed with this job was that we all just got on so well. The chemistry is right – and I guess [lead writers] Russell T Davies, Chris Chibnall and [executive producer] Julie Gardner knew that it would be."
The writers, in fact, know a lot of things, muses Naoko.
"We recently filmed a scene where Tosh gets her favourite Chinese takeaway delivered and it's hot and sour soup and fried squid with pepper and chilli. Now those are really my two favourite dishes!" she laughs.
"I was really freaked out by that. How did they know? We've never been out for a Chinese or even discussed it! I've basically come to the conclusion that Russell and Chris are from another planet and they have X-ray vision. They're genius aliens who can read minds."
Aliens in Cardiff? Sounds like a case for you know who...
Roll on week 49!
