Each dancer will perform three times on tonight's So You Think You Can Dance -- two partner dances and one solo. And back as a guest judge is Debbie Allen, who was awesome a few weeks ago. So it promises to be a fun night.

Pasha's partner for the week is Lacey, and they draw hip-hop with Dave Scott and smooth waltz. In their hip-hop routine, Lacey is a mannequin for a large part of the performance, and Pasha has nerd glasses. It's an amusing routine, but I think it kind of wastes Lacey's talents since she is still for so much of it. But yeah, I will be watching it again. Nigel says it was a great routine and that it "brought your characters to life." Mary says this was crazy because she couldn't believe it was Pasha out there. Debbie says they were lucky to get Dave's name out of the hat and that they nailed it.

Sabra performs the first solo of the evening. It is -- as per usual -- fantastic, and she's adorable.

Lauren and Danny are partnered up, and they draw contemporary with Mia Michaels and disco. The contemporary routine is supposed to be very "alien." I think if they hadn't mentioned that, I wouldn't have seen that in the performance at all. Even with hearing that, I don't see it much. But it's still a moving performance (though I could have done without the Celine Dion). Nigel: "Incredible!" He adds that he feels Lauren finally reached her potential. Mary Murphy screams and adores it. Debbie says it was "passion and perfection personified."

Next is Pasha with his solo, and he's dancing around a dress form with an evening gown on it, which is ... odd. Does he wish it were Jessi?

Neil and Sabra are partnered for jazz with Mandy Moore and paso doble. The jazz dance is supposed to be evoke a 1980s business meeting. They dance together around a table, and my husband looks up from World of Warcraft just long enough to note, "Is it prop day on So You Think You're Dancing With the Stars?" The concept is a little out there, but it really works with the song ("Sweet Dreams" by the Eurhythmics), and they are great together. Nigel says he is very worried because he hopes the finale (next week!) comes up to the standard set today. Mary says she's still smiling and that it was "really so much fun." Debbie sums it up, "I like it like that."

Lauren dances her solo, and you know what? Her hamminess has annoyed me this entire season (somehow more than Lacey's), but she has really been dancing better and better. Sigh.

Lacey and Pasha's second dance is smooth waltz with Hunter Johnson. It's lovely and definitely lives up to its name. Nigel says the flow was absolutely beautiful. He says one tiny weakness was Lacey's hand position. Mary says it was "absolutely dreamlike." She says that Pasha freaks her out because he has adapted so well to the hard ballroom steps that are alien to Latin dancers typically. Debbie compares this to a love story and says that everyone wanted to be them. Basically, raves from everyone.

Neil's solo shows, to me, how much less he is relying on gymnastics, which he did a lot during the first part of the season.

Danny and Lauren come out to dance disco by Doriana Sanchez. And this one I found a little bizarre. I didn't like the song or really the choreography, but I thought they danced it well. Nigel says this was a really tough routine and that disco makes him happy to watch no matter what, and that he liked it. Mary says it was a ton of fun. She adds that Lauren looked like the queen of the 70s and that Danny is breaking out more than they've seen from him before. Debbie says they had fun so the audience had fun.

Lacey comes out to solo to "Le Disco," which is not very disco-ish. She is all over the stage, and it's doesn't feel like a partner dancer forcing a solo, which happens sometimes.

Sabra and Neil are the last duet of the evening, with the paso doble with Tony Meredith. The look amazing, and they both deliver exactly the attitude they are supposed to have. And the end is CRAZY -- Neil has Sabra hoisted over his head, and she is folded around his arms, holding onto her feet, and he lets go, and she kind of falls, in increments, to the ground. Insane and very cool. Nigel: "Wow, that was absolutely stunning." He also says he wouldn't have thought at the beginning, but does now, that either of them could win this thing. Mary credits Tony and Melanie's choreography and says that they "did tremendous." She says they are both back on the train, and Neil notes it's his first time on the train. Debbie says she was sure she didn't want to see the paso doble again (have I mentioned that I love Debbie Allen?), but that they were fabulous.

Danny is the final soloist, and he is great. (If I had more dance knowledge, I would have more to say about it, but I don't.)

Host Cat Deeley says that two dancers will be going home from the next results show, which is on Monday (anybody know why?). Then the final four will perform next week.

I don't really know who will be out. Pasha and Lauren? I just can't imagine that either Lacey or Sabra would be out, but who knows? What do you think?
