Good point, maybe that could be how the next episode opens, then Sansa goes up into the tower and lights a candle or whatever it was that Winterfeller told her to do if she was in trouble. Although Sansa's such a calamity she'd probably expect the cavalry to break down the gates and rush in to save her only to find that no-one's awake to see the candle in the tower
“The larger the group, the more toxic, the more of your beauty as an individual you have to surrender for the sake of group thought. And when you suspend your individual beauty you also give up a lot of your humanity. You will do things in the name of a group that you would never do on your own. Injuring, hurting, killing, drinking are all part of it, because you've lost your identity, because you now owe your allegiance to this thing that's bigger than you are and that controls you.” - George Carlin
