Alison sits with her legs either crossed, or if not then they are always close together, with her hands resting on them
Cosima mostly leans on her arm length. Or is leaning back completely on whatever she can. Or sitting in the traditional Japanese way called ‘Seiza’ where one sits on their own lower legs.
Sarah, the punk that she is, whether leaning or not, sitting on a table, ground anything, always has her legs apart.
Helena sits hunched over indicating her hostility & anxiety.
