Oliver made everything at least 75% better. I disliked Mallory a lot sometimes, because she was
self-centered and a bit selfish at times, but well, I'm sixteen too, so I understand when accidentally we forget to think about others. I was ambivalent about the Mum: she was... unlikable, I think -- but well, my mother would win the Mother Olympics, I think, so there's that. Still, I liked that she cared about her daughters (even if, as Mallory said, she cared about "the wrong things"). Ginnie was absolutely adorable and the Grandmother was great.
But, um. Oliver took the cake.
