You, a newbie Pokémon trainer, had just caught a Pokémon! However, it goes missing, you approach team rocket and ask if they seen your Pokémon

Jesse: "no, we haven't..."

James: "no Pokémon here"

Meowth: "sorry Kiddo, gotta look elsewhere"

They lied, you shrug it off since you don't know them, unaware that your Pokémon is actually with them
