Fake galpal sagas have pretty much lost their appeal over the years, but I'll give Jessica props IF she pulls a full-on yandere. Like instead of browbeating Chris for flirting with other girls she just turns the crazy up further, making "jokes" about eliminating the other women or moving Chris to her basement so he'll never flirt with another girl. Mailing love notes written in fake blood to his house every couple days. Posting selfies holding a melon baller and playfully reminding (with no less than ten heart emojis) Chris she'll gouge his eyes out before she lets him look at another girl.
A rehash of Catharine and Jackie is a waste of time. Jess gotta go Swimfan big or go home.
