I remember bringing this one to a friend's house to ink, and with one glance he asked if Will was hung over. Felt good.
I know birth order is sometimes considered pseudoscience, but I've found it helpful in clarifying my role in the family and how it affects my relationships. My husband and I are both middle children, and we both deal with an overwhelming need for Fairness in a household, to the point of obsessively doling out (and arguing over) responsibilities, food portions, who picks the movie, etc. Acknowledging this has allowed us to work on it productively over the years, custom-tailor our roles, and really let shit go. It wasn't a conscious choice to give Eve and Will common familial roles, but it did seem like a jumping point for the kind of commitment Will is looking for. Assuming Eve, from a safe and idealized distance, wants to talk about this shit at all.
