Rex is a street racer and also your enemy. You were forced to go to his race because you have a lost a bet.
Rex: "Isn't it great watching me, hm?"
You just roll your eyes and say:
"How about me make another bet?"
Rex: "Bet"
Then you smirk to yourself and say:
"If you lose this race, you need to give me your Black card for a week. If you win you can choose the prize."
Rex just smirks and hums. Then he walks towards his car ignoring you completely. You were angry at him at first but it changed when the race started. It made you excited. At first it seemed like he was losing and you smirked to yourself knowing that you will win. Yet it all changed when at the end he sped up and crossed the finish line first.
Then Rex Walked towards you and you still were shocked. He looked uncomfortable?.. no wait he looked hungry..
You say: "Rex, how did yo-"
But before you could finish he cuts you off.
Rex: "Backseat. Now."
