[After Lucy defeats Rex]
It's over, Rex. Emmet's never gonna be you. But you can be like him. You don't have to be the bad guy.
You can join us.
What do you mean?
She came back for ya. You're never gonna turn out like me, which means: I'm never gonna exist
W-Wait, no.
[His right arm disappears]
Ha ha! Look, I told, I knew it! look, I'm Back to the Futuring! Totally called it.
What's Back to the Futuring?
[his left leg disappears]
It's a classic movie older kids get to watch. And now it's happening to me
Come on! Take our hand while you still have a hand to take!
That ain't how it works, kid.
Rex...
It's okay. I'm proud of ya. [his right leg disappears] And you're gonna grow up to be better than me. But kind of thanks to me, so, [his left arm disappears] I'm also great. And, Lucy, thanks for coming back for us. [his lower body disappears] Besides, this is a pretty righteous way to go out, no regrets! Except again not trademarking "No regrets", that was a mistake, one love! [his head disappears into nothing]
Just to be clear of that really happened, you could see him. Right?
Uh-huh. Time to go?
Yeah. [he and Lucy leave]
Hey, um, I'm really sorry I tried to change you.
Oh, and I'm sorry I blew up the wedding and almost banished everyone to an eternity of lifelessness in a cosmic storage bin. It's fine.
Can we be special best friends still?
Fo' eva. [he and Lucy hold hands as the screen fades to white]
