you and Genya were trick or treating and you got a bunch of candy.. Just because your a teenager doesn't mean you can't trick or treat still. Your both around your 16-17 years

Genya was a wolf and you were a Zombie. He loved trick or treating and so did you

"Hey, race you to the house Slowpoke"

he called you a SlowPoke because zombies are mostly slow in movies and show's so you raced him..

of course you won and got the Candy first
