All these years of planning and now William was exactly where they wanted him]

[the two go the woods. Inside the couch]
Sci-Ryan: Before you ask what else did Odette want to say to Derek, she and I want to know that she loves him for just being her.
Guard: [off-screen] Whoa! Whoa.
[The carriage comes to a halt]
Sci-Ryan: Something's wrong. I think we stopped.
King William: Stay inside with Sci-Ryan, Odette.
[Just as King William was about to step out, Rothbart and Ryvine motion a wave of magic around them before throwing their fists toward the ground sending a flash of light. By the time the light fades, a demon and a ghastly creature emerges and before everyone could react, the 2 beasts suddenly trusts toward the couch with a great ferocity. At Queen Uberta's castle]
Ryan F-Freeman: I hope Sci-Ryan fine.
Thomas: I hope he is, Ryan. You did well comforting Queen Uberta.
[Ryan nods and hears Sci-Ryan's Goofy yell]
Evil Ryan: That sounds like Sci-Ryan. It sounds like.... like he's in trouble.
[A door to Uberta's castle burst open, causing Prince Derek, Ryan and the gang to turn as a guard comes to the room appearing as if he came out of a losing battle before collapsing on the ground. Quickly, they rush to check up on the story]
Crash Bandicoot: Oh my gosh!
Evil Ryan: That's one of William's guards. What happened?
Guard: We... We were attacked. A demon and a Great Animal....
Matau T. Monkey: Sci-Ryan.
Rigby (EG) and Derek: Odette.
Ryan F-Freeman: Meg. Bertram. Evil Anna. Stay with Queen Uberta until Derek gets back.
Meg Griffin: Ok, Ryan. Good luck.
[Ryan and the gang follow Derek to where he's going]
Crash Bandicoot: I hope we're not too late.
[But by the time they got to the couch, they could see that it has been demolished, as if torn apart by a vicious creature]
[In the woods, Bee jolts Raf awake]
Raf Esquivel: What's wrong, Bee?
Bumblebee: Something's happened to Sci-Ryan. We have to find him.
Raf Esquivel: Look. Derek! You got here to where the couch is.
Crash Bandicoot: Sci-Ryan! Odette! Where are you?
Derek: Odette? Odette!
Evil Ryan: Sci-Ryan!
[But no matter how hard they look, all they can find of Sci-Ryan and Odette were Sci-Ryan's amulet and the very same locket he had given her the very moment Derek first met the princess. Suddenly, some soft moaning draws the groups attention]
Emmet: [gasps] Guys! Come over here! Quick!
[They turn to see King William, laying limply on the ground and clutching his chest in agony]
Rigby (EG): Dad!
Sir Kylo Ren: Brother.

Ryan F-Freeman: I would, Sonata, but.. I fear I can't.
Rigby (EG): I hope my dad will come back as one of those blue ghosts.
Mordecai (EG): I hope he will, Rigby.
Derek: Where is Odette?
King William: Listen to me, Derek. Listen... All of you. It's not what it seems. It's not what it seems.
Raf Esquivel: What does it mean?
Derek: What's not? Where is Odette?
Evil Ryan: And Sci-Ryan?
King William: Odette... Sci-Ryan... Are... Odette... Sci-Ryan... They are... Gone.[dies]
Sir Kylo Ren: Bro? Bro? [sniffs] He's dead.
Ryan F-Freeman: SCI-RYAN!!!
Derek and Rigby (EG): ODETTE!!!
Crash Bandicoot: Oh, King William. Your sacrifice for Odette and Ryan F-Freeman of Crystal Prep will not be in vain.
Cody Fairbrother: Why is Rigby saying "Odette"?
Ryan F-Freeman: I think he might be related to her somehow.
Rigby (EG): By my magic, I will find you, Odette. [runs off to find Odette] My sister.
Flain (EG): Guys? Where is Rigby going?
Crash Bandicoot: I think he's running after the demon and the Great Animal. He needs our help.
Ryan F-Freeman: Derek. If I'm not back with Odette, tell my girlfriend, Meg Griffin, that I've got killed by the Great Animal with your love and Sci-Ryan. And I love her.
Evil Ryan: Go to Uberta's castle, Derek. That is all I can say for now. We will speak again.
Derek: Ok, Evil Ryan. Good luck.
[Derek watch as Ryan and his friends set off to find Sci-Ryan and Odette. Derek goes back to Uberta's castle]
Derek: Meg. I got some sad news. Your techno-organic boyfriend is killed along with Odette and Sci-Ryan.
Meg Griffin: Oh no. [starts crying]
[Bertram goes to comfort Meg]
Bertram T. Monkey: There, there, Meg. Shhhh. I vow that on my master, Xehanort, I will help you and Derek find the demon and the Great Animal.
[The song I Will Go Sailing No More starts playing as Evil Anna walks down the halls sadly]
Morgana (Persona 5): Out among the stars I sailed~
Way beyond the moon~
In my silver ship I've sailed~
To a dream that ended too soon~
Now, I know exactly who I am and what I'm here for~
Sci-Ryan: [voice] Evil Anna. Morgana is born a cat! He can't fly!
Morgana (Persona 5) And I will go sailing~
Evil Anna: But, no~
It can't be true~
Morgana (Persona 5) and Evil Anna: I (He) can fly if I (he) wanted to~
Morgana (Persona 5): Like a bird in the sky~
I beleave I could fly~
Why, I'd fly!~
Morgana (Persona 5): Clearly, I~
Evil Anna: Will go sailing~
Morgana and Evil Anna: No more~
[Evil Anna starts crying because she thinks Sci-Ryan is dead and Morgana comforts her. Queen Uberta comes over to see Evil Anna]
Queen Uberta: Evil Anna? What is the matter?
Evil Anna: Oh, your highness. I think Sci-Ryan got killed by the Great Animal and the demon.
