Okay, so my boyfriend and I had an interesting realization about the Starks and their dire wolves.
As a general rule, the Stark wolves are in similar situations and the Stark they are connected to. Robb dies, his wolf dies. Arya is out the woods, so is her wolf.
That only leaves the question of Sansa. Her wolf is dead but she is not.
We started talking about it and came up with an interesting idea. She herself may not be dead, but since she is having to transform herself to fit in in King’s Landing, maybe her Stark side has died?
Personally I do not know, just some food for thought. Also didn’t read the books, just have watched the show and that it what we are basing this off of.
