We should start with some quotes from GoT while everyone is waiting for the upcoming season.
With pleasure.
S1
Jaime : "Robert will choose a new hand of the kingdom to do his job while he's out fucking boars or hunting whores... or is it the other way around?"
Yoren : "What about you, milord. What's the strangest thing you've eaten?"
Tyrion : "Do Dornish girls count?"
Robb : "Any man of the Night's Watch is welcome at Winterfell."
Tyrion : "Any man of the Night's Watch but not I, eh boy?"
Robb : "I'm not your boy, Lannister."
Tywin : "You spend too much time worrying what other people think of you."
Jaime : "I could care less what anyone thinks of me."
Tywin : "That's what you want people to think of you."
Tyrion (to Bronn) : "Though I would treasure your friendship, I'm mainly interested in your facility with murder."
Jaime : "If your gods are real, if they're just, why is the world so full of injustice?"
Cat : "Because of men like you."
Jaime : "There are no men like me. Only me."
S2
Matthos : "And I declare on the honour of my House that my beloved brother Robert left.."
Stannis : "He wasn't my beloved brother. I didn't love him. He didn't love me."
Davos : "A harmless courtesy, Your Grace."
Stannis : "A lie. Take it out."
Davos : "If not Renly Your Grace, join forces with Robb Stark."
Stannis : "Who'd steal the northern half of my kingdom? I've always served thieves according to their deserts, as you well know Ser Davos."
Ser Meryn : "No one threatens His Grace in the presence of the Kingsguard!"
Tyrion : "I'm not threatening the king, Ser. I'm educating my nephew. Bronn, the next time Ser Meryn speaks, kill him. That was a threat. See the difference?"
Jaime (to Cat, being dragged off in chains) : "You've become a real she-wolf in your later years. There's not much fish left in you!"
Yara : "Are you the dumbest cunt alive?"
Theon : "Don't call me a.."
Yara : "A cunt. A dumb cunt who killed the only two Starks in Winterfell."
S3
Jaime : "Ah, Renly. Really? He wasn't fit to rule over anything more important than a 12-course meal."
Un-named Karstark man : "Mercy, sire! I didn't kill anyone. I only watched for the guards."
Robb : "This one was only the watcher. Hang him last so he can watch the others die."
Brienne : "Why didn't you tell Lord Stark?"
Lannister : "Stark? You think the honorable Ned Stark wanted to hear my side? He judged me guilty the moment he set eyes on me. By what right does the wolf judge the lion? By what right?" (collapses in the bath)
Brienne : "Help! Help! The Kingslayer!"
Jaime (weakly) : "Jaime. My name is Jaime."
Jaime (to Roose Bolton) : "Give my regards to Robb Stark"
Cersei : "Do you know where House Reyne is now?"
Margaery : "Gone."
Cersei : "Gone? A gentle word. Why not say slaughtered?"
Tywin : "Explain to me why it is more noble to kill ten thousand men in battle than a dozen at dinner."
If it isn't obvious, my favourite character is Jaime. I hope my favourite Jaime moment from the book makes it into the show. It's minor in the big scheme of things, but sums up his redemption quite nicely.
