Hi! Skye is definitely leaning on the bratty side! One of the reasons she is such a fan favorite is because of that! She gets mad at the MC mostly because it seems like they forgot about her during those days! She has never really experienced rejection or not being pursued before (And she also never experienced real attraction before your arrival at the academy), so she reacts in unexpected ways! This is also tied to the setting at the beginning of her story with her family and Red.
As for the second question, actually yes!
