Dannii: "Joe, I just have to say the voice is exceptional and you are an absolute star, honestly. What I loved about that performance is it's the first time we've seen you moving in amongst the audience and you absolutely looked so comfortable, and they adore you."
Louis: "On paper, I didn't think this was going to work. It's a big, big rock anthem. But you absolutely won me over. The little boy has become a man, and Joe, don't stop believing. I believe you're going to be in the final."
Simon: "Joe, you're one of the most consistent performers we have in the competition. Whatever's thrown at you, you do your best. It was a little bit limp and stage-schooly in parts, but the singing was excellent."
Cheryl: "I loved it. You know what it is Joe, you sometimes even impress me because you give that extra 20%. All of the north east is rooting for you, and the calls I'll get tonight about this performance will be through the roof. You're going all the way to the end."
Louis: "I loved you last week when you sang jazz and I loved you this week when you sang rock. You're one of the most versatile contestants and professional performers in this contest. You can sing anything and Simon, I think you owe her an apology for last week. You are great."
Cheryl: "Last week, you totally won me over and I started to think maybe this is the direction you should go in, maybe you should be this singer. And then tonight I started to think maybe she should be an Avril Lavigne-style singer. I'm impressed, you did a great job with a tough song. Well done."
Simon: "Let me go back to last week. The reason I didn't like you was because you were boring. And this is what's frustrating me - you're a good singer, 18 years old, and you were being made to be old-fashioned. However, tonight I take that back. Because on paper this shouldn't have worked, but you gave it 100% and made yourself contemporary. I agree with what Cheryl said - it was an Avril Lavigne-type performance. You're starting to find direction as a real teenage pop artist."
Dannii: "Well I was absolutely taken aback by the rockiness that came out in your voice this week so thank you for rock week. That's the comment you wanted [from Simon] so I'm so proud and happy for you. Enjoy it."
Dannii: "Danyl, it's always a tough one for anyone who lands in the bottom two to get back on the stage, and at some point other people in the competition are going to have to go through that so we know how you're feeling. I felt like it was sad to see, you've lost your mojo. I feel like you've been stripped back too much and it's not your natural performance. At the end of the song you hit your stride and the big notes were fantastic, but it was out of tune right at the beginning then throughout. I just want to see you get up there and rock it."
Louis: "I want to be absolutely honest with you. There's no way you should have been in the bottom two last week, absolutely no way. This is a talent show, and you're a very talented guy. I know you've had a setback, but I want people at home to give you a second chance. You have something special. Pick yourself up and get back in the race, because that's life."
Cheryl: "I'm finding this a little bit uncomfortable to be honest. You've obviously had a massive dent to your confidence, and it's apparent. Rachel was in the bottom two for the first two weeks and she came out and fought for her position. That's what you needed to do. You do it, you do everything well, you just don't do it for me."
Simon: "Here's the problem, you've got contradictory things going on here. When he comes out confident he's cocky, when he decides to tone it down he needs to be cocky. I think I know what the issue is, and it's nothing to do with being in the bottom two. When you have to read headlines like you're the most hated contestant, it's going to affect you. Having said that, you've got to take it on the chin. You're still probably the best singer still in the competition. I genuinely hope the public vote for you this week, Danyl, because you deserve it."
Dannii: "Lloyd, I bet every one of your female fans wishes that was sung about them. You're the heartthrob. It was a great performance. I found at times your voice was drowned out by the track. I would love to hear something a bit more melodic, but it's the most comfortable you've been on stage, so well done."
Louis: "Lloyd, listen, when I said I'd put you in a boyband that was a compliment. I think you're a great little pop singer, but the theme this week was rock and you sang a pop song. You slightly cheated. But I really like you, I know girls are going to vote for you, but you're going to have to start singing better."
Simon: "Louis, you've got to stop believing you create the rules in this competition! You're becoming so boring. What was good about tonight is you're only 16, it was a quirky song, and it made you relevant. The vocals at the beginning were actually pretty bad, but in the second part of the track you got more comfortable. It was a million times better this week than it was last week."
Cheryl: "You know what, Lloyd, we took a great risk. Every teenage girl, especially girls on Facebook, are going to wish you were singing that about them, and you know what, you are a little popstar. No, you shouldn't be in a band, because everyone loves you just how you are. On your own."
Louis: "Stacey, you're definitely the most popular girl. Everywhere I go people love you. You're very consistent, you tick all the boxes. I wasn't crazy about the song choice - it was a little bit boring - but I love you."
Cheryl: "I'm actually going to totally disagree. I loved that song choice for you. The thing we love most about you is your personality, and I want to see more of that, because I know you're definitely going to be here next week. A bit more personality in your song and you're swimming, you're there."
Simon: "It's extraordinary, that was like an X Factor miracle tonight. You walked! Literally, I mean, I'm more impressed with you walking than you singing. As I said, you haven't moved in three weeks. I thought it was a good choice of song, I think it made you relevant... I thought it was terrific. One of your best performances."
Dannii: "She can walk, she can move! I loved the performance and we're going to see you here next week, so vote Stacey!"
Dannii: "Jamie, you're absolutely in your element when you're doing that kind of song. I know that's your roots, where you come from, and you don't need to hide that at all. It was a great performance, but for me there was something special when you performed the song 'Hurt'. There were whispers you were going to do a different song, something to make you contemporary rather than doing an old rock song, but you're an amazing performer and singer."
Louis: "Jamie, it was a great performance, but like I said on the VT there's nothing original about you. There are 100 guys doing what you do in pubs. You're like a Lenny Kravitz impersonator, but it's not real rock. In the world of Kerrang and NME you're not a real rocker."
Cheryl: "There's never been a rock week on X Factor before, then all of a sudden Simon has a rock act and we have rock week. Weird. Anyway, that was the most comfortable, original performance you've given so far, so well done."
Simon: "Are you saying that I chose this week... that's spiteful. The problem is Jamie, once again, what do you do? You came from that background, you want to be a rock singer, it's rock week, and you choose a rock song. What else are you supposed to do? I don't get it - I thought of all tonight's performances this was the most authentic. You were terrific tonight."
Louis: "Rachel, it was an incredible song choice. I didn't think it was a good idea on paper, but you made that song your own. It was very emotional, soulful, vulnerable... in fact it was the most emotional performance of the entire night."
Cheryl: "It was a very, very clever song choice, because Mary J Blige did that with U2 and you got to show the soul in your voice. Your voice is my favourite out of the girls and you deliver every week."
Simon: "I liked the last third of the song. Where I had a slight issue was that Dannii is trying to turn you into her with the hair, the dress... I just felt your whole look, therefore presentation, made the song a bit cabaret."
Dannii: "Rachel, that was amazing, an amazing performance. It was great because you just allowed yourself to be vulnerable. It reminded me of when I saw you at the judges' homes with Kylie and it was just us in the room and you just sang. It's just about your voice."
Dannii: "Well, it is Halloween, and that was quite scary. I think you almost needed a satnav to find your way back to the lyrics at some point. I look forward to seeing you every week but I'm not sure I'd look forward to hearing you on the radio. You've really got to listen to the song."
Cheryl: "The production was absolutely fantastic, everything going on. You're definitely dressed for the occasion - Halloween. Yeah, I felt like I was rocking to that song. I don't know what to say!"
Simon: "Well, it was night of the living dead. Singing Queen out of tune, possibly destroying Queen's career forever. Look, guys, I credit you with tenacity. You've stayed in the competition, you're thick-skinned. However, you cannot, cannot defend that singing tonight."
Louis: "It's all about a show. It's two young kids living their dream. They're having fun, the audience love them, they're energetic, entertaining, exciting... this is what the music business is all about. Kids everywhere, all they want to see is John and Edward."
Dannii: "Olly, I have to say I absolutely adore you. You are hot, hot, hot and the moves get better every week. The vocals are consistently brilliant. I'm not sure about the hair but I love you."
Louis: "Olly, I think you're the dark horse in the competition. You keep getting better, you're the one artist that gets better every time we see you. You get more exciting. I think you're in the final three."
Cheryl: "You're definitely the most progressed contestant in this competition. You come into yourself more and more each week. You really impressed me tonight."
Simon: "Olly, I think as Louis said you're progressing better than just about everybody right now. Now you've reached the point where you've got confidence and you're learning how to perform. You sound like a credible artist, and I'm very, very proud of you, Olly. You did a great job."
