"The problem is, we won't have any supply lines. Any food that we eat, we'll have to forage for, and it's nearly the end of autumn, which would make things even harder. If it starts snowing, all Ramsay has to do is sit in Winterfell while we freeze to death and die from hunger out in the cold. And once the winter snows start falling, moving a large number of troops will become nearly impossible. Even if we wanted to visit only half the houses in the North, it'd take nearly a year to travel around, putting us in a far worse position than now. The more we wait, the worse our chances are. If we wait for my dragons to grow up, all they can do is burn Winterfell and not hold it, which is something I greatly want to avoid," Jon countered.
