Gone and down - that's it gone.

Bruce Mouat shakes his head ruefullly. The Great Britain skip has left his last stone just in sight of his United States counterpart John Shuster.

Shuster clears it out and we have another blanked end.

Valieva is down again. Once again there are so many emotions watching this 15-year-old skate amid a drugs test storm.

The crowd is trying to lift her.

Down Kamila Valieva goes!

After a shaky start, some of which she had held together, she hits the ice.

There is surely no way back...

So then.

Kamila Valieva emerges onto the ice.

If she comes out on top that will not be the end of this story. There will be no medal ceremony. The story of her drugs test will rumble on.

Kamila Valieva is on the ice, having a final warm-up before she skates in the most controversial circumstances.

For the four minutes of her Bolero routine, though, the focus will be on the skating.

It's supreme from Russian Anna Shcherbakova.

Her compatriots are on their feet in the stands.

She goes into the lead!

One skater remains and, with the world watching, it's Kamila Valieva.

How many people are taking extended lunch breaks to see this to the end?

It could well be a Russian 1-2-3 here.

Japan's Kaori Sakamoto, who was third after the short programme, is way off Alexandra Trusova's massive score and sits second with two to go.

Next it's Anna Shcherbakova - the world champion - and then of course, Kamila Valieva.

Kaori Sakamoto's routine is lovely, it's very, very good, but it does not include the difficult moves the Russians have packed in.

She scores a season's best but it's only enough for second.

Trusova keeps the lead and only the two other Russians, Anna Shcherbakova and Kamila Valieva, remain.

On we go...

Still trying to get to grips with the story that has dominated these Games? It has been revealed Kamila Valieva failed a drugs test in December but...

When the Russian Anti-Doping Agency (Rusada) received word on 8 February that Kamila Valieva had failed a drugs test, it provisionally suspended her in line with Wada rules.

Valieva appealed against the decision - on what grounds, it is so far unclear - and Rusada agreed to lift the suspension the following day.

The International Olympic Committee (IOC), World Anti-Doping Agency (Wada) and the International Skating Union (ISU) then launched an appeal with the Court of Arbitration for Sport (Cas) to get the provisional ban re-imposed.

The Cas hearing was only ever about the provisional ban - it was not considering the positive test or the circumstances around it.

It decided that because of Valieva's age and the "untimely notification of the results" of the failed test - in the middle of the Games and nearly six weeks after she gave the sample - that it would do her "irreparable harm" if she were not allowed to compete.

So, she can take part in the women's event which reaches its climax today.

But the issue of the failed drugs test will still need to be resolved and no time frame has been given for this, which in part is why there will be no medal ceremony.

Under Wada rules, if an athlete's A sample is positive, then they may request that the B sample is tested. It is not yet known whether Valieva has asked for this.

A fist pump from Alexandra Trusova at the end of her routine, she knows that was seriously good.

And the 17-year-old Russian has gone straight to the top of the leaderboard - there are gasps all round when the score comes up. She has a total of 251.73, which is well over 30 points clear of the next best skaters.

That is what quads get.

The Russian contingent in the crowd is on its feet after Alexandra Trusova nails a routine packed with difficulty.

There are gasps as the score is announced. She gets a massive 177.13 for that routine, taking her to 251.73 in total - a lead of 36.

Kaori Sakamoto is next. Can she break up the Russians?

This is more like from Matt Hamilton.

The American has been a bit quieter than his skip so far, but after a good bit of brushwork early in the sixth end, he thrashes his broom handle like he is playing guitar.

Alexandra Trusova means business - three quads down, two to go. She is putting everything into lifting herself up from fourth.

In that figure skating final Japan's Wakaba Higuchi has put herself top of the standings, gliding around the rink to a Lion King medley.

ROC's Alexandra Trusova is up next. She is planning the hardest routine of all in a bid to get into the top three.

We're heading into the most intriguing hour or so of the 2022 Winters so far, and you've got a choice to make.

GB men's bid to upset Mr T and Team USA in the curling competition will reach its climax soon. That will continue on BBC One or at the top of this page.

If you hit the Red Button (or click on it via this page), we'll be showing Russian skater Kamila Valieva, who is favourite to win the women's figure skating free skating event. If she did place in the top three, medals will be held back because of her failed drugs test pre-Beijing.

More on that story here.

Over to you!
