Robb ____ a force to retake Winterfell by now.
Робб, должно быть, уже отправил войска, чтобы отвоевать Винтерфелл.

THEON: If I find them soon enough, I won’t hurt them. Well, I’ll hurt them, but I won’t kill them.
LUWIN: Those boys are of far more value to you alive than dead.
THEON: They have no value to me missing.
LUWIN: Robb will have sent a force to retake Winterfell by now.
THEON: Robb’s in the Riverlands.
