Game of Thrones, Season 4

Samwell Tarly:
We held them off.

Jon Snow:
For one night.

Samwell Tarly:
This is a great victory!

Jon Snow:
Great victory? Mance was testing our defenses. He almost made it through. And, he has more giants, he has more mammoths; he has a thousand times as many men. They'll hit us again tonight. Maybe we can hold them off for a day or two, but we'll never beat them.

Samwell Tarly:
Where are you going?

Jon Snow:
I'm going to find Mance.

Samwell Tarly:
To fi- you can't do that! No one gave you any orders!

Jon Snow:
Who's left to give orders? The Wildling army is only an army because of Mance. He united a hundred warring tribes. Without Mance, they lose their leader, they lose their purpose, they go back to fighting each other, scatter back to their homes.

Samwell Tarly:
Without Mance. You goin' to kill him?

Jon Snow:
I'm gonna try.

Samwell Tarly:
They'll never let you within a hundred yards of him! And even if they did, even if you managed to kill him...

Jon Snow:
They'll kill me. But if I don't go, they'll kill me anyway. They'll kill the rest of us, too.

Samwell Tarly:
They won't just kill you. They'll boil you, they'll... flay you, they'll make it last days!

Jon Snow:
You're right. It's a bad plan. What's your plan? [they find the last giant dead, surrounded by the bodies of Grenn and the other five Watchmen] They held the Gate. Get some brothers down here to help you. We need to burn the bodies. Raise the outer gate, then lower it again as soon as I'm out.

Samwell Tarly:
[notices Jon unbuckling Longclaw from his belt] What're you doing?

Jon Snow:
I promised Mormont I'd never lose it again. [hands the sword to Sam] In case I don't come back.

Samwell Tarly:
Jon? Come back. [Jon gives him a sad smile and walks out beyond the Wall]
