Vivian Kensington
When I watched the movie for the first time I liked that Vivian and Elle became best friends at the end, but this last viewing I was so against it. I know it represents Elle being accepted and Warner not but it doesn't feel right anymore.
Also, I don't really like how Vivian forgives Elle for thinking Elle was having an affair with Callahan. Emmett says one thing and Vivian is quick to agree. I know Vivian was warming up to Elle before she saw Elle and Callahan together, but it just doesn't go with her character. She took 2 steps forward in being friends with Elle but the situation sent her 3 steps back rather than just 1, imo.
