It'll be the end of Chanel #3's life when Hoffel founds out that she knows there's other green meanie besides Cascade, she's in such a difficult position tbh, telling the other Chanels that Cascade is one of the green meanie is too risky but could be the way to prove to us that their friendship is really strong by maybe agreeing to Chanel #3's request no to turn him in to the police because she love him, and work together to figure out who the other killer is.
And to think Zayday is nowhere near Chanel #3's level in figuring out who the killer is after all ha effort

Really lovin' the screentime Chanel #3 got in this episode, she really is the smartest and level-headed among the three
