Lemon is uncharacteristically jealous. Just because she cheated and feels bad about it doesn't mean that George would. Of course Zoe probablly *shouldn't* haven't gotten carried away with her inpromptu speech, but still. It was complimentary.
I think Zoe would call her father for many people who were in need, not just George. Wade needs to grow up and start doing something with himself, or he'll always be on the outside. Lemon needs to let go of ALLLLL her anger. Wow sister got issues!
