... I’m pretty sure Catelyn stark is the one that wanted Jon to be legitimised as neds son and this was years ago when he was young and she treated him as her own son if Neds is bring this up then he is holding a grudge like a woman men tend to think better of their other half’s in my opinion and I’m pretty sure Catelyn became unstable in the books and show after the deaths of most of her children and husband so this one has no actual reason to be unstable and infact she should support a fellow northern for the king ship especially if it will protect her family from getting involved in the game
