Luka: Hey, I've been trading e-mails with Carter.
Abby: Really? Did you tell him about us?
Luka: No... he needs help in Sudan. And he asked me if I would join him.
Abby: In Africa?
Luka: I'd be back before the baby's born.
Abby: Oh, o.k. O.k. I mean, uh, were you planning on talking to me about this?
Luka: I am talking to you. If you don't want me to go.
Abby: You don't need my permission to go.
