In any season that most if not all the ladies dislike one particular woman, the same thing happens time and time again. It happened in Jake's season with Vienna and in Ben's with Courtney, each of them got protective. In the end, Jake chose Vienna and Ben chose Courtney. Granted neither relationship lasted long, but each season could have ended differently.If the ladies were truly smart, they would learn from past season's of the show. If a particular girl isolates herself, don't concern yourself with her, spend the time with the girls who want to be friendly. But most of all, don't try to warn The Bachelor about the other girls, it always backfires on you. Make every conversation with The Bachelor about the two of you.
If the other ladies had only ignored Tierra and her antics, she might already be gone.
