Of the Stark Children:
Rob - dead
Jon (maybe not a Stark) - dead, but potentially resurrected by the Lord of Light - thus becoming less than he was.
Sansa - helpless AND a pawn of the man who conspired to kill her father.
Rickon - unable to walk, but learning some new skills
Arya - becoming not-a-stark (at least, that is where the House of B&W wants her)
Bran - MIA (seriously I'm not even sure I remember where Bran is in the books?).
Seems like a lot of the Stark-iness in Westeros is disappearing, huh?
IF Stannis is dead, all the Stags are gone now, so sorry House Barantheon, you played the GOT, and lost.
Bran is training to become a Tree Jedi in the north.
Also Rickon is what...8 by now? He should be walking. He would be a great playmate for Tommen when the Lannisters capture him.
