@Kukothemadhatter I think you're getting their characters a little wrong. Caroline by no means is innocent, she's already been through ups and downs in relationships and professionally, she's a strong independent woman who is very caring, loving and considerate, especially toward MC, they've always been extremely close. It's Sara that is the most unstable, it's her first love, that teenager's puppy love thing, she's devoted to MC, she's insecure, shy, she's the one not to take rejection or betrayal lightly, she'd be devastated. Linda isn't manipulative nor scheming, she's just highly erotic woman, a woman that knows what she wants and she's not afraid to go and get it, and it wasn't until MC trying to get with Celia, the teacher, that made Linda act, she got jealous, she realized that her son, her love interest is out to look for a partner, if she doesn't act now, she'll lose her chance.
