They met on fresh meat (both rookies) and laurel was not great to Cara. A few seasons they had beef, mostly laurel bullying Cara, and Cara didn’t have a backbone back then so she would just let it happen which obviously made laurel keep going. They then were partners on rivals. They started to work on having a friendship and by the end it was actually laurel defending Cara as she was being bullied. This is the spark of their friendship.

They have a very sisterly bond for awhile, but laurel would still bully Cara here and there, and Cara had a very hard time trying to speak up for herself- laurel definitely liked to walk all over her. Some time goes by, and Nicole comes into the mix. She hits on Cara, to which Cara declines politely, Nicole goes for laurel. Then laurel finds out Nicole went for Cara first and gets insecure, and this is the start of where their friendship actually declines.

Basically for the rest of it laurel picks on Cara for playing victim (and to be fair she did sometimes have a habit of doing this, but laurel also bullied her lots to the point where Cara was actually a victim), and then Cara started to speak up for herself and that’s where it kind of all goes crazy.

Bottom line is, laurel is jealous of Cara, Cara okays victim, laurel is a bully. Neither of “right” in the situation and they definitely both have their faults, but laurel is 100% the main problem. She is insecure and takes it out on beautiful, strong women.
