It exists, the morning after the preps party. Riona tells her she's having a bad hangover (as in Rooster) and Heather inquires about who decided to go to that party, if that's only a one-time thing and why it was neccesary, as she thinks HOT's are earning enough money. She also bitches about 6 new girls having to live in the HOT's house, that's gonna be crowded. Riona doesn't want to give her any details and finally says it's all Sage's idea, and Heather agrees it's time for her to pass the torch as president
Edit- I have just look at the script and it's a canon scene, it plays in every path. No requirements. It's just before Camila tells Quinn about Mona backing out
