I think Corinne is a misunderstood bad girl. I don’t think she’s an inherently nasty person, but it seems like she’s been raised to think that being harsh and aggressive is the best way to get through life. The reason I’m thinking she’s not inherently like that is that she seemed genuinely sympathetic towards Paloma, including in the voting confessional, where she had no reason to put on an act.
Interesting theory. You may be on to something.
