EDIT: here is the whole dialogue:
"I prayed for my son Bran to survive his fall. Many years before that, one of the boys came down with the pox. Maester Luwin said if he made it through the night, he'd live, it would be a very long night. So I sat with him all through the darkness. Listened to his ragged little breathes. His coughing, his whimpering.
Jon Snow. When my husband brought that baby home from the war I couldn't bear to look at him. I didn't want to see those brown stranger's eyes staring up at me. So I prayed to the gods, take him away. Make him die. He got the pox. And I knew I was the worst woman who ever lived. A murderer. I'd condemned this poor, innocent child to a to a horrible death all because I was jealous of his mother. A woman he didn't even know. So I pray to all seven gods, let the boy live. Let him live, and I'lll love him. I'll be a mother to him. I'll beg my husband to give him a true name, to call him Stark and be done with it. To make him one of us.
[And he lived?]
And he lived. And I couldn't keep my promise. And everything that's happened since then, all this horror that's come to my family, it's all because I couldn't love a motherless child."
EDIT: i'm quoting Francis Buck from another thread, because I think it's interesting:
Catelyn's story about Jon was...weird. It doesn't bother me, necessarily but it was definitely a strange addition. It's one of those instances (like Dany's vision of the Iron Throne destroyed and covered in snow) where I feel like the showrunners know important things about the end of the series, and thus are purposely foreshadowing events that the book readers could have no inkling to. I really don't think they just make up random shit like that for the sake of it (though that's how many book readers seem to feel).
