I get why you would defend Sara and I do agree with that part, but what makes you call Caroline trash? I mean, apart from Sara and Linda, Caroline is the only one who DOESN'T use MC for their own personal, selfish gains, and yeah, even that photoshoot stuff in her store and those "rewards" don't count.
Aunt Yazmin uses MC to introduce dick in her sex life with MC's aunt, get her used to it, so that Yazmin can express her own sexuality more liberally, since she's not full on lesbian like Aunt is.
The twins used MC for financial gains.
Celia humiliated MC publicly.
