After a heartfelt surprise proposal -- Will you marry me? Heck, yes. Reporter: -- Encouraging parents and meaningful reflections. I have found the confidence I never thought was ever possible. Reporter: A shocker in the ballroom last night. All coming down to two front-runners. Nastia and Derek. Reporter: But even after receiving all perfect marks Monday golden girl nastia liukin was sent home. I definitely wanted to make it to the finale. Reporter: Facing her fair share of hurdles. It seems like you're frustrated. That's not something that I'm going to talk about. Reporter: Both personal. Seeing that package was just really upsetting. I just wanted to scream out that's not me. Reporter: And on the dance floor. In week seven partner Derek hough five-time mirrorball champ sidelined by injury. I can't dance. Reporter: Fans hoping for a full-on return sometime soon after Derek danced a slow waltz on Monday night. That was the most special dance I think I've ever seen. Reporter: But in the end the gymnast couldn't quite clinch the gold. I just want to say thank you to everybody for giving me such an amazing experience. Toets ? Ah, so beautiful. Nastia and Derek, come on out here. Come on out here. Oh. Hi. How are you both? Good to see you, Derek. We're back. Feels like yesterday we were here. I know. Feels like forever and yesterday all at the same time. You know, congratulations on getting as far as you did. You had the perfect score on Monday. Week in and week out you were at least in the top three so were you as surprised as everybody else. You know, not really. I feel like on Monday night first of all being able to dance with Derek one last time really meant so much to me and that dance was kind of the perfect way to go out. It was such a special moment. Not only to share with Derek but with Len and be able to tell his story of his career, so it really was a special dance and, yeah, I mean I definitely didn't want to leave but it was a good night. Felt like a little send-off but it was very special. Your sister said she was an emotional wreck? That show in general, everybody was so fantastic. You know, I think, you know, Noah was sensational. A moment where he closed his fist and I was like, that's it. In the moment I knew he was going to the finals and he deserves to be there. Just been a fantastic season and ironic, just an interesting one too because, you know, having her dance with two different partners and, you know, and handling that so flawless a eneffortlessly. You playing with so many pain. How do you feel right now. I feel good. I'm healing extremely fast which is good because I tart rehearsals for tour tonight back in L.A. So -- You're going back to L.A. Tonight. Yeah. So it's -- I'm doing good. But she's -- it was great to be able to dance with her one last time and with Len too. Do you think all the travel back and forth you were doing the residency in New York and radio city, did that play a part in your opinion in sort of keeping it as tight as it could be? I don't know. You know, funny, this morning we flew back here and we haven't been flying back and forth because of my injury but we missed that. That kind of back and forth. Chaotic. Were you doing moves by text. Videoing and a routine where we had two rooms. She was going from one room to the other in her yief and kind of represented her experience on the show because she was going back and forth with partners each week. I love how you jumped when you do the back story pieces, you're a good partner but the remaining three, who do you all think? Who is going to take home the mirrorball trophy. So hard to say. I mean, every single couple has a different strength and that's what's so cool to see. Riker has been like amazing from day one but I think his moment was the pirates moment that he had. He like was in character the entire day and then Rumer and Val have been incredible showing that emotion and chemistry and Noah has just been such an inspiration to all of us and any time we -- I know any time I want to complain about anything it's like you have no excuse. No reason to complain. It's been a fantastic season watching. A great attitude. Congratulations. We haven't seen the last of either one of you. No, you haven't. I'll see you guys shortly. I know. Always, always. Get a chair for you you're on so much. We love you, Derek. Good job. "Dancing with the stars" finale starts next Monday at 8:00 eastern, 7:00 central right here on ABC.
