The other Gilmore- Jess Mariano

Cordelia Gilmore is the "bad twin" in stars hollow. She has long, dark, layered chocolate brown hair with piercing green eyes, an athletic small frame.
Despite her great contribution to the stars hollow lacrosse team, the whole town is practically scared of her due to her infamous habits of fighting.
She works party time at gypsys car shop. She regularly goes to the diner with her mom and sister, she has high walls and never feels like she's good enough due to her constant comparison to her golden sister, so she rebels out of spite most the time.
She has a very good heart but hides it, she does stuff like charity work, and goes to the animal shelter a lot to volunteer. She also suffers from anxiety and anger issues what most people don't know about, only mainly luke lorelai and Rory know the whole truth.
One day, she woke up late for school, lorelai and Rory were at the diner already when she bursts in with her headphones rather ungracefully and sees Luke standing next to Jess.
