OMG TYSM! And yes, Hazel is the introvert of the three (and will ironically be the tallest one lmao). Also, I didn't realize it till now that Cherylle does give off step one Elizabeth vibes. She's sadly a meanie to Qiu, Tamarack, and everyone around her during step one but mellows out in the later steps. Ebony on the other hand got some layers to her (that would be revealed in later steps) but she's a ray of sunshine mostly throughout step one.
And you're totally fine with the pronouns, all of them follow she/her pronouns in step one. Cherylle is the only one that switches pronouns (she/her, they/them) in the later steps.
