Any goodbye (like the one in King's Landing) and/or homecoming (like Cat coming home to Winterfell for the first time) would do. But I'm specifically interestedin the ones surrounding Balon's Rebellion. Arya was born the same year as the rebellion so was Arya already born when Ned left? Or was she born while he was gone? Or born after he returned? Considering that, what would have Cat and Ned's parting and reunions have been like?
