Randyll Tarly, to his son Sam when he comes home:
"I thought the Night's Watch might make a man of you. Something resembling a man, at least."
Yara Greyjoy, to her sad-sack brother Theon after he complains about his luck in life:
"Fuck justice then. We'll get revenge."
Yara Greyjoy, saying goodbye to her brother right before grabbing a friendly woman at the bar:
"Now, since it's my last night on shore for a while, I'm going to go fuck the tits off this one."
Tormund Giantsbane, on the subject of loyalty:
"We're not clever like you Southerners. When we say we'll do something, we do it."
Olenna Tyrell, to Cersei after she makes a threat:
"You've lost, Cersei. It's the only joy I can find in all this misery."
Olenna Tyrell, again to Cersei, this time after she tries to make a truce:
"I wonder if you might be the most horrible person I've ever met."
