Two routines and one solo apiece later, the top six has left their fate in the hands of voters, and it's not going to be easy.

With their individual dances down, the pressure seemed to release as the top six paired off for the final three pieces of the night.

Sasha and Ricky paired up for a fun and funky waacking routine (yes, that's actually a style of dance) that only left the judges wanting more.

"I truly enjoyed the fun of it," Nigel said. "[Especially] Sasha, wow you were fabulous!"

Ricky said it was a brand-new experience that didn't come easy.

"The hardest thing ever," he shared after the show. "I don't know anything and when they told us we had it, I said, 'Sasha, are you ready for this?' I loved it. I didn't think it was going to be that much fun. Our choreographer made it so much fun. It was like learning ballet in two days...I enjoyed myself on stage today."

Melanie and Tadd took on a Broadway piece that left Nigel eating his words and changing his mind about who his favorite dancer is.

"You are a brilliant actress and an incredible dancer," he said. "You're back to being my favorite dancer."

When we chatted with Melanie after the show, we asked about Nigel's "favorite" flip-flopping between her and Sasha.

"We are roommates and we really haven't [talked about it]," she said. "I don't really hear what he says to anybody else."

The night closed out with Caitlynn and Marko performing a contemporary routine that had Nigel clapping just a few seconds in. At the end, all the judges were on their feet in a standing ovation.

"Best number ever for you, Caitlynn," Mary said. "You brought true grit to it."

"Caitlynn, you came of age tonight," Nigel added.

While many have pegged Sasha and Melanie to be the top two girls left standing, Christina said Caitlynn's performance could change that. 

"I think it was kind of clear for awhile [who would be in the top four], but we had a dancer who had a huge breakthrough tonight. She got a standing ovation, so you never know."
