Let's talk about this character's personality and how she was handled so uniquely.

What's interesting about her is that she appears in only 7 episodes.
The way everyone swoons over here and says her name might make her seem like a mary sue, but in reality that's because of her naturally appealing personality. She acts like a popular jock because she is one. If she was male you'd instantly see that this in fact a popular jock in female form.
