One thing I always notice about Emma is how she takes up space. The way she'll just lie on MM's bed at different points in season one seems too familiar to me, for people who've just been roommates for a little while... especially for as emotionally insecure/distant Emma tries to be with people in s1. I feel like that has to be a conscious decision on Jen's part, and I try to figure out what motivates Emma to be like that.
