Game of Thrones, Season 7

Bran Stark:
Come in. [Sam enters] Samwell Tarly.

Samwell Tarly:
I wasn't sure if you'd remember me.

Bran Stark:
I remember everything. You helped us get beyond the Wall. You're a good man.

Samwell Tarly:
Oh. Well, thank you, but, um, I'm not sure that I am. What happened to you beyond the Wall?

Bran Stark:
I became the Three-Eyed Raven.

Samwell Tarly:
Oh. I don't know what that means.

Bran Stark:
I can see things that happened in the past. I can see things happening now, all over the world. Why did you come to Winterfell?

Samwell Tarly:
Jon's the one to lead the fight against the dead. I know he is. But he can't do it alone. So I've come here to help him.

Bran Stark:
He's on his way back to Winterfell... with Daenerys Targaryen.

Samwell Tarly:
Y-you saw this... in a vision? [Bran holds up a scroll] Oh.

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:
He'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!

Bran Stark:
Are you certain?

Samwell Tarly:
It's what the High Septon wrote in his private diary. I don't know why he'd lie. Is there something you can see?

[Bran has a vision of Lyanna and Rhaegar's wedding]

Rhaegar Targaryen and Lyanna Stark:
Father, Smith, Warrior. Mother, Maiden, Crone. Stranger. I am hers/his, and she/he is mine, from this day until the end of my days.

Bran Stark:
Robert's rebellion was built on a lie. Rhaegar didn't kidnap my aunt, or rape her. He loved her. And she loved him. And Jon... Jon's real name...

Lyanna Stark:
[to Ned Stark, in flashback] His name...is Aegon Targaryen. You have to protect him. Promise me, Ned.

Bran Stark:
He's never been a bastard. He's the heir to the Iron Throne. He needs to know. We need to tell him.
