Massive Damage
Part 4: The Storm
The thing I like about Mary is the fact that she always has other people do things for her. For example, she was told to call Joel's Dad, but instead, it's revealed by Liz that she decided to follow Eric and Joel's fight. It's implied that she told Liz to call Joel's Dad for her, so she can follow the fight, and avoid the conflict of talking to Mr. Heyworth or getting involved in Kevin's fight with the rock monsters (which is still going on at this point). I think that's a very intriguing quality that Mary has. It may come into play later.
