Toni: You don’t own the color red. Red existed before you.
Cheryl: Not at Riverdale High. Here, I invented red. I am red.
[Cheryl snaps her fingers and two girls stand behind her]
Cheryl: Sorry, but this school is not big enough for the both of us, faux-pink lady. And I was here first. Go to Centerville High or Westerberg, I don’t care. But you have until first bell Monday to clear every trace of yourself out of these halls. Copy?
[Cheryl flips her hair in Toni’s face and walks away]
