Olivia didn't enter New York until she was around 8, so probably wouldn't have known her unless she'd gone to the same school as her. I'm not sure they got along very well. They seem to be complete opposites. Olivia is very private and not one for sharing, hierarchy is a big deal for her. The fact that they're both stubborn doesn't help, either, and neither does the fact that she's in another sorority. We'd have to play it out, but I'm not sure they'd get along very well.
