Bran Stark: He needs to know the truth.
Samwell Tarly: The truth about what?
Bran Stark: About himself. No one knows. No one but me. Jon isn't really my father's son. He's the son of Rhaegar Targaryen and my aunt, Lyanna Stark. He was born in a tower in Dorne. His last name isn't really Snow, it's Sand.
Samwell Tarly: It's not.
Bran Stark: Dornish bastards are named Sand.
Samwell Tarly: At the Citadel, I transcribed a High Septon's diary. He annulled Rhaegar's marriage to Elia. He wed Rhaegar and Lyanna in a secret ceremony.
Samwell Tarly: These maesters... they set me to the task of preserving that man's window counting and annulments and bowel movements for all eternity, while the secret to defeating the Night King's probably sitting on some dusty shelf somewhere, completely ignored. But that's all right, isn't it? We can all become slavering, murderous imbeciles in thrall to evil incarnate as long as we can have access to the full records of High Septon Maynard's 15,782 shits!
Gilly: Steps. That number was the steps.
Randyll Tarly: How'd you come to meet my son?
Gilly: The Night's Watch came to our keep.
Randyll Tarly: Where?
Samwell Tarly: Gilly.
Gilly: North of the Wall.
Randyll Tarly: North of the Wall? You're a wildling. The Seven Kingdoms have waged war against these savages for centuries and here I sit hosting one in my hall! Thanks to my son...
Jon Snow: Sam. You had just been beaten half to death. How did you...
Samwell Tarly: Oh, very carefully.
Jon Snow: I'm glad the end of the world's working out well for someone.
Jon Snow: You know that the Citadel will make you swear off women, too.
Samwell Tarly: Oh, they'll bloody try.
Samwell Tarly: If Gilly stays here, then she'll die. And the baby that she named after me will die. And I'll end up dying, too, trying to protect them. Which means that the last thing that I'll see in this world will be the look in her eyes when I fail them. And I'd rather see a thousand white walkers than see that.
Samwell Tarly: His name was Aemon Targaryen. He came to us from King's Landing. A maester of the Citadel, chained and sworn, and sworn brother of the Night's Watch, ever faithful. No man was wiser or gentler or kinder. At the Wall, a dozen lord commanders came and went during his years of service, but he was always there to counsel them. He was the blood of the dragon... but now his fire has gone out. And now his watch is ended.
Janos Slynt: How's your lady love, Slayer?
Samwell Tarly: Her name is Gilly. Brother Slynt knows her quite well. They cowered together in the larder during the battle for the Wall. A wildling girl, a baby, and Lord Janos. I found him there after the battle was over. In a puddle of his own making. Whilst Lord Janos was hiding with the women and children Jon Snow was leading. Ser Alliser fought bravely, it is true, but when he was wounded, it was Jon who saved us. He took charge of the Wall's defense, he killed the Magnar of the Thenns, he went North to deal with Mance Rayder. Knowing it almost certainly meant his own death. Before that, he led the mission to avenge Lord Commander Mormont. Mormont himself chose Jon to be his steward. He saw something in Jon. And now we've all seen it too. He may be young, but he's the commander we turned to when the night was darkest.
Samwell Tarly: He'll make you a Stark with a stroke of a pen.
Jon Snow: It's the first thing I ever remember wanting. I daydreamed that my father would ask the king. Just like that I would never be the Bastard of Winterfell again.
Samwell Tarly: No, you deserve this. You do. I-I couldn't be happier for you.
Jon Snow: I'm gonna refuse him.
Samwell Tarly: But... you'd be Lord of Winterfell.
Jon Snow: I swore a vow to the Night's Watch. If I don't take my own word seriously, what sort of Lord of Winterfell would I be?
Samwell Tarly: So what's it like?
Jon Snow: It's... there's this person, this whole other person. And you're wrapped up in them and they're wrapped up in you. And you... for a little... for a little while, you're more than just you. You're... I don't know. I'm not a bleeding poet.
Samwell Tarly: The interesting thing is, our vows never specifically forbid intimate relations with women.
Jon Snow: What?
Samwell Tarly: "I shall take no wife," yes, that's in there. There's no denying that. "I shall father no children." It's very specific. But what do our vows have to say about other... activities is open to interpretation.
