This is how Odette gets revived and the spell on Ryan is broken goes in Crash, Thomas and Ryan Meet the Swan Princess.
Ryan F-Freeman: [pants] Wow. That was a battle.
Sci-Ryan: Yup, Ryan. But, you're stuck as a swan. Meg will make a vow to you.
Evil Ryan: Hold it, fellas. Now is not the time. Look.
[Ryan and the others look at Derek with Odette laying on the ground]
Derek: Forgive me, Odette...
Crash Bandicoot: [sighs and starts crying]
Derek: Forgive me. I only wanted to break the spell, to prove my love. I love you of your kindness and courage, I always have.
Sci-Ryan: And Derek loves you of your loyalty and the friendship of me.
[Derek kisses Odette on her forehead. Sci-Ryan places some flowers on the floor and places his hand on his chest]
Odette: Derek? Sci-Ryan?
Meg Griffin: [gasps] She's alive, Ryan.
Ryan F-Freeman: Let's watch.
[Then Ryan and the gang were surprised to see what happened. Odette, in some way and some how, was alive as she looks up to Derek with loving eyes. Derek was shocked as well, but the moment he saw her eyes he knew at once what had happened. His love... Saved her]
Odette: Oh, Derek!
Sci-Ryan: [gasps] ODETTE!!! You're ok!
Odette: Sci-Ryan? Why are you happy?
Sci-Ryan: Oh, Odette! You're alive! Derek's vow of everlasting love broke the spell on you!
Odette: Yes, Sci-Ryan. And your friendship helped.
Mal (Total Drama): Stepping away.
Crash Bandicoot: Fleeing are we? You can never rule Odette's father's kingdom. Every power Rothbart has is gone and Rothbart himself is now been exterminated! Tonight, you have showed Ryan and Odette what you truly are. You have showed us what's in your heart.
Mal (Total Drama): [looks at Ryan in his swan form then at Sci-Ryan] I... I... I am sorry. I'm so sorry for letting Rothbart manipulate me to locking Flain up. I don't know if I can forgive myself.
Sci-Ryan: Mal. The Magic of Friendship is everywhere, even in Odette's world, Equestria, other worlds, throughout time and all dimensions. You can ether seek it out, or you can forever be alone like Rothbart. The division is yours.
Mal (Total Drama): Sci-Ryan. All I ever done since Rothbart helped me lock up Flain is my desire to rule Equestria. Although his magic destroyed some of my memories of being friends with Flain's human friends, I can't remember anything about friendship anymore.
Princess Ivy: Poor Mal. My dragonflies didn't drain his memories.
Red (Angry Birds): Mal lost his memories!? It's Crash, Thomas and Ryan meets Sofia the First: The Curse of Princess Ivy all over again.
Sci-Ryan: I will help you regain those memories, Mal. The Mixle Dramas however gone to the Dark side of the force. If I'm not mistaking.
Ryan F-Freeman: That's a good thing to do, Sci-Ryan. But, there's one thing. How am I suppose to show myself at the Autobot Base while I'm stuck as a swan for crying out loud?!
Meg Griffin: Calm down, Ryan. I can help you break the spell.
Evil Ryan: Everypony. Listen to Meg please.
Meg Griffin: Ok, everyone. I have something to say. I have been Ryan's girlfriend since he met me as a kid. We went on so many adventures together from helping Thomas fit in at CHS to finding the Key to Vector Sigma. But, now. I will make a vow to Ryan. A vow more powerful like the Magic of Friendship and Derek's love to Odette. Thanks to Derek, I found Ryan. Before you and before everyone here in Odette's world. I made a vow of everlasting love...
Evil Ryan: Please be Ryan. Please be Ryan. Please be Ryan. [to Rigby (EG)] What? I can dream, can't I?
Meg Griffin: To Ryan F-Freeman. The Prime-prince of Friendship.
Ryan F-Freeman: That's nice of you, Meg. I made my vow to be with you.
Mal (Total Drama): [in Mr. Potato Head's voice] Who invited that kid?
[Before Sci-Ryan can say something, Ryan feels magic coming around him. Sci-Ryan, Odette, Derek and Meg watch as Ryan becomes engulfed by the magic and when it clears up, Ryan has became a human in his Odette outfit. The spell on Ryan has been.... broken]
Sci-Ryan: [in awe] Whoa. That's what I saw Odette. [faints]
Ryan F-Freeman: What happened? Odette? Derek? Meg?
Derek: Ryan. You are Odette's friend?
Ryan F-Freeman: Yes, Derek. I thought up a nice plan to help Odette reunite with you and Meg did the same for you.
Crash Bandicoot: Wait. Is that a bit cool. Derek is in love with Odette while Ryan's in love with Meg?
Meg Griffin: Oh, Ryan. I'm so happy that you're yourself again.
Ryan F-Freeman: I'm happy that you made a vow to me, Meg. [kisses Meg]
Puffin: Sci-Ryan. Wake up. Please.
Sci-Ryan: [gets up] I'm up. What happend to Odette?
Mighty Eagle: Odette is alive and Ryan is with Meg. Looks like Ryan became the Swan Prince and a smitten kitten.
Rianna F-Fiona: We should sing a song to Derek and Meg.
[the song the Mighty Red song starts playing]
Ryan and Odette: Meg and Derek, you rescued me~
Defenders of our love and liberty~
Evil Ryan: Bravery~
Evil Rianna: Humility~
Red (Angry Birds): Happily~
Ryan and Odette: Meg and Derek you~
The Cyberlings and the Cyberlanders: La, la, la, la~
Crash Bandicoot and Crash Bandicoot (EG): La-la-la, la-la-la-laaaaaaaaaaaa~
Sci-Ryan: Great Scott.
Mal (Total Drama): [in the Mime Bird's voice] Oh my Gahh.
Matau T. Monkey: Sorry Morro tried to stop Nightmare Moon from putting a spell on you.
Mal (Total Drama): I... I forgot what I was going to say.
Crash Bandicoot: Rothbart was our nemesis. Bad Sofia joined Rothbart and try to force Ryan to marry her. But it's all over now. They can't do anything to us anymore.
Coco Bandicoot: Well said, big brother.
Crunch Bandicoot: Wow! We're getting a lot of Dalek and Cybermen junk all over the woods.
Cody Fairbrother: We're not going to clean these up.
Ryan F-Freeman: I know, Cody. I know.
Mal (Total Drama): Yup. Like that outfit, Ryan. It does match mine.
Ryan F-Freeman: Except it's black and red, Mal.
[Flash Fire goes to Ryan]
Ryan F-Freeman: You come to finish me for Rothbart?
Flash Fire: Ryan... I realized my mistake of joining Rothbart. Even you turned into a swan. I surrender. You win.
Ryan F-Freeman: Wow.
Sci-Ryan: Look, FF. The Magic of Friendship is everywhere, even in Odette's world, Equestria, other worlds, throughout time and all dimensions. You can ether seek it out, or you can forever be alone like Rothbart. The division is yours.
Flash Fire: But, Crystal Prep's Ryan. All I ever done with Rothbart and Ryvine is my revenge on Ryan and my former teacher. [sniffs] I guess.... I don't know the first thing about friendship.
Bumblebee: [beeps] (translation: "I bet Matau and the Skylanders and the Rowdyruff Boys can teach you.")
Flain (EG): That's my best bud!
Mal (Total Drama): I'm so sorry for betraying you, Flain. You can stay at Crystal Prep.
Flain (EG): Yes. Sci-Ryan needs me to help the other Shadowbolts.
R.J: Well done with the vow, Meg!
Rianna F-Fiona: We should make Swan Lake Odette's and Derek's castle now.
Ryan F-Freeman: You said it, Rianna. Now that with the help of Sci-Twi and Bromley, Rothbart is now gone.
Rigby (EG): [hugs Odette] Oh my sister. You're alive! My sister. Friend of the Swan Prince.
Evil Ryan: Flain is a Shadowbolt now. [uses his magic on Mal]
Mal (Total Drama): Uh. No. Evil Ryan. Don't do this. No one will ever cross you with me as Flain's friend. I'm a part of Mike.
Ryan F-Freeman: Yes, Mal. A part of Mike that he don't need anymore. I never forgive you, Mal. Goodbye now.
Mike (Total Drama): It's time to join Rothbart, Mal.
Mal (Total Drama): No! NO!!! I will have my revenge, Ryan! Flain will be my friend! I will forgive him! It's MY time! MINE!!!!!!!!![disappears from existence]
Derek: He's gone!
Crash Bandicoot (EG): Holy cow.
R.J: See you never, Malevolent One.
Matau T. Monkey: Aww. Master Ryan, Odette, Meg and Derek are together. [looks at the camera] And there you have it, folks. A vow of everlasting love.
Puffin: You said it, Matau.
