Claire: What kind of world is this to bring a baby into?
Jamie: The only world.
Claire: No, it isn't. Jamie, I want Brianna and Roger to go back to their own time as soon as they know if Jemmy can travel. It's safer for them there. For Jemmy especially. Roger feels the same way. He wants to take them home.
Jamie: Of course he does. Your penicillin will make it safer for them here, will it not?
Claire: Only from infection.
Jamie: Well, perhaps it will be safer in your time, but they will be without their family, without their blood.
