Imo, she needs a backstory, things that happened to her in the town she used to live... Maybe family history too(Nyx is using with Val's mom the same trick she uses with Layla/Alexis dad and always shoots her from the back, always obscuring her face)... and those need to connect to her current personality/attitude.
Who were those pics in her phone for?
Did she have a boyfriend who fucked around on her? Maybe backstabbed by one of her friends...
Things that explain is she so non-chalant about shanking other chicks and just "tries" every option available, even Darryl who anyone can see is a douche from a mile away.
She does have the most "wannabe suitors" with Darryl, Zach and maybe the gym instructor...
