Serena: It's like our sleepover seeing the dinosaurs up close in Jurassic World.
Ash Ketchum: Yeah, but it's already destroyed. Really wish it was never been destroyed. We would've go there together to have fun.
Ash Ketchum: So all we have to do now it's to find the first piece of the heart jewel and then we'll find our friends and get out of the island tomorrow morning.
Ash Ketchum: Good night, Serena. Good night, Pikachu.
Serena: Good night, Ash. Good night, Pikachu.
