Ms. Rolly will find out Ferrah's secret.
I think somehow when Ferrah goes home, her mother is crying for her and wanted to know what is going on. No way out of this, she transform into her werewolf form in front of her mother to show why she hasn't shown up to her and apologizes for not revealing her secret. Her mother hugs Ferrah, saying it's alright and accepts her for what she is.
Nikki will be helping Ferrah after finding out her secret.
After recovering from a hospital, she will be calling her to meet her in a park. By the time she gets there, Ferrah is confronted by Nikki at gunpoint. She asks her what is going on and Nikki replies that she knows her secret. What else is that she's gonna kill her so that the world will be safe. Realizing this, Ferrah understands and let her get killed.
However, Nikki can't find herself to do it and cries to Ferrah about it because she can't kill her friend. Ferrah does the same, believing it's her fault that she didn't tell her secret to her.
After comforting each other, Ferrah transforms into her werewolf form to show what she really is. In return, Nikki reveals her secret of being a slayer, then she holds hands with Ferrah as she plans on helping her.
John Sterling is Ferrah's father.
Well, who do you think training her to control her powers?
