Figure skating isn't usually known as a blood sport, but American figure skater Mirai Nagasu was bleeding during the Ladies' Short Program event.
So what happened?
It turns out she was having a nosebleed. She says it was brought on by Canada's cold, dry air, but some experts thought it could be caused by the high-speed spins she's known for.
"Spinning so fast, sheâs caused a nosebleed maybe." said one commentator.
âThe spin itself could have put extra pressure on the blood vessels in the nose,â said Dr. Gwen Korovin.
The 16-year-old from Los Angeles kept right on skating, despite the blood.
"Halfway through the program, I felt it running down my nose and just said, 'Don't stop, keep going,'â Nagasu said.
Her brave performance earned her 6th place going into the finals.
And there was more drama at the rink. 24-year-old Joannie Rochette took to the ice just two days after her mother's death from a heart attack.
She burst into tears at the end of her short program, covering her mouth to stifle her cries.
Cameras cut to her teary-eyed father giving his daughter a standing ovation.
Veteran skating commentator Scott Hamilton's voice broke as he watched the scene unfold.
"The skate and the moment means much more than the competition," Hamilton said.
Rochette sobbed in her coachâs arms. Going into the finals, she's in third place. No doubt mom would be very proud.
And there's even more drama at the Olympics. Actor Walter Koenig, famous for playing Mr. Chekhov in the original Star Trek has turned up in Vancouver, making a desperate plea for help finding his missing son.
âThere are so many people out there who really care about him,â Koenig said.
His son is Hollywood actor Andrew Koenig, who played Boner in the series Growing Pains. Andrew went to Vancouver to attend the Olympics and has been missing ever since, triggering a desperate search.
