Go to King's Landing with your family
From Create Your Own Story
Cately is ecstatic with your decision, as is Sansa. The former happy to head south once again, and no doubt looking forward to seeing her sister once again. The latter has her head filled with knights and songs, and you only hope that she doesn't become disappointed with what she finds in the south. Arya, is simply angry that her bastard brother can't come for the journey, and has no desire to leave Winterfell, it might be best if you find a way to make it up to her.
Robb is left in charge of Winterfell, and will have to deal with Mance Rayder and the threat beyond the wall if it comes to it, you pray that it wont.
The Journey South is Long and tiring, it is best to get it done with quickly.
