Kit Harington

Tyrion Lannister: "Let me tell you something, Bastard. Never forget what you are, the rest of the world will not. Wear it like armor and it can never be used to hurt you."
Jon Snow: "What the hell do you know about being a bastard?"
Tyrion Lannister: "All dwarfs are bastards in their father's eyes."

Jon Snow: "You don't have the discipline. You don't have the training. You're army is no army. You don't know how to fight together."
Ygritte: "You don't know that."
Jon Snow: "I do. I know it. If you attack the Wall, you'll die. All of you."
Ygritte: "All of us. You're mine as I'm yours. If we die, we die. But first, we'll live."
Jon Snow: "Yes, first we'll live."

Jon Snow: "Stick 'em with the pointy end."
Arya Stark: "I know which end to use."

Samwell Tarly: "Ser Alliser's going to make me fight again tomorrow, isn't he?"
Jon Snow: "Yes, he is."
Samwell Tarly: "I'm not going to get any better, you know."
Jon Snow: "Well, you can't get any worse."

Jeor Mormont: "Honor made you leave, and honor brought you back."
Jon Snow: "My friends brought me back."
Jeor Mormont: "I didn't say it was YOUR honor."

Jeor Mormont: "When dead men, and worse, come hunting for us in the night, do you think it matters who sits the Iron Throne?"
Jon Snow: "No."
Jeor Mormont: "Good. Because I want you and your wolf with us when we ride beyond the Wall tomorrow."
Jon Snow: "Beyond the Wall?"
Jeor Mormont: "I will not sit meekly by and wait for the snows. I mean to find out what's happening. The Night's Watch will ride in force against the wildlings, the White Walkers, and whatever else is out there. And we will find Benjen Stark, alive or dead. I will command them myself. So I will ask you once, Lord Snow, are you a brother of the Night's Watch, or a bastard boy who wants to play at war?"

Snotlout: "Could this day get any worse?"
Tuffnut: "Uh, lemme see: We're jumpin' in freezing cold water, and then die from drowning."
Eret: "Looks refreshing."

"You can do good, or do well."
