>>>Then Connor’s lips were parting, and the words Lester wanted to speak were flooding from his mouth.<<<

I really like this characterization. Connor can be overly naive at times, but his ultimate charm comes from his openness and compassion. He knows he shouldn't be revealing the secret, but he can't stop himself from giving Emma the answers she needs to make sense of what's happening.

Hmmm... lots of sticky complications now. I wonder how Human!Lester will deal with the aftermath in his family life (assuming he does get his old body back).
