Viewers saw some impressive numbers, a leap through the air, a potentially disastrous wardrobe malfunction and the second perfect score of the season.
William Levy and partner Cheryl Burke danced their way to a perfect 30 score for their Foxtrot.
"I never thought about getting three 10s in this competition," Levy said, "so when I saw the 10 coming out and the other 10 and the third 10, I was like, 'What?'"
They came back with triple nines for their dance trio routine with pro dancer Tony Dovolan in round two.
One point behind them on the judges' leaderboard were Roshon Fegan and partner Chelsie Hightower. They placed strongly for the only two left who have been in the bottom two.
"It feels great, it feels perfect," Fegan said. "We've been working real hard and making sure that we got back to the top, and we're here."
Tied for third were Donald Driver and partner Peta Murgatroyd. Their trio dance with Karina Smirnoff included the most daring move of the night, when Driver leaped through the air.
"She said let's see if you can jump over both of us at the same time. I told her I needed her shoulders, and it worked," Driver said. "I just didn't want my booty to hit Karina in the head."
Tied for third with Driver and Murgatroyd were Katherine Jenkins and partner Mark Ballas. They had a scary wardrobe malfunction with Jenkins' tear-away suit during their dance trio Cha Cha.
"It's weird because that suit is made exactly in half, so when the boys rip it off, there shouldn't be a bit below the knee left, and we still can't work that out," Jenkins said.
Maria Menounous and partner Derek Hough landed in fifth place, followed by Melissa Gilbert and partner Maksim Chmerkovskiy.
The scores are close. Once viewer votes are factored in, any team could go home. Tuesday night, two teams will in a double elimination.
