Erin will forgive. Mothers always forgive their sons. Oh wait, she isn't his mother, she only looks old enough to be his mother.
And does anyone know what ever became of the guy Erin fell so madly in love with on FLOM? She behaved like a skank on FLOM both times she was on it, so maybe she shouldn't act too high and mighty in her forgiveness of Will. He may have flirted, but he was very careful not to cross the line in terms of what he did with Janelle, which I respect him for.
