Show stannis has said that speech almost word for word, but in a completely different context. Show stannis is kinda naive, completely Melisandre's pawn, and eagerly wants to be king cus it's his right.
book stannis is just different, his lines are inbold. last stannis chapter before surprise rescue at the wall:
Melisandre moved closer. "Save them, sire. Let me wake the stone dragons. Three is three. Give me the boy."
"Edric Storm," Davos said.
Stannis rounded on him in a cold fury."I know his name. Spare me your reproaches. I like this no more than you do, but my duty is to the realm. My duty..."He turned back to Melisandre."You swear there is no other way? Swear it on your life, for I promise, you shall die by inches if you lie."
chapter before that one:
"I am not seeing the body, no, Your Kingliness," said Salladhor Saan. "Yet in the city, the lions prance and dance. The Red Wedding, the smallfolk are calling it. They swear Lord Frey had the boy's head hacked off, sewed the head of his direwolf in its place, and nailed a crown about his ears. His lady mother was slain as well, and thrown naked in the river."
At a wedding, thought Davos. As he sat at his slayer's board, a guest beneath his roof. These Freys are cursed. He could smell the burning blood again, and hear the leech hissing and spitting on the brazier's hot coals.
"It was the Lord's wrath that slew him," Ser Axell Florent declared. "It was the hand of R'hllor!"
"Praise the Lord of Light!" sang out Queen Selyse, a pinched thin hard woman with large ears and a hairy upper lip.
"Is the hand of R'hllor spotted and palsied?"asked Stannis."This sounds more Walder Frey's handiwork than any god's."
"R'hllor chooses such instruments as he requires." The ruby at Melisandre's throat shone redly. "His ways are mysterious, but no man may withstand his fiery will."
"No man may withstand him!" the queen cried.
"Be quiet, woman. You are not at a nightfire now."
"More?"Stannis looked as though he would gladly have throttled her."More usurpers? More traitors?"
"I have seen it in the flames."
Queen Selyse went to the king's side. "The Lord of Light sent Melisandre to guide you to your glory. Heed her, I beg you. R'hllor's holy flames do not lie."
"There are lies and lies, woman. Even when these flames speak truly, they are full of tricks, it seems to me."
"Give me the boy for R'hllor," the red woman said, "and the ancient prophecy shall be fulfilled. Your dragon shall awaken and spread his stony wings. The kingdom shall be yours."
Ser Axell went to one knee. "On bended knee I beg you, sire. Wake the stone dragon and let the traitors tremble. Like Aegon you begin as Lord of Dragonstone. Like Aegon you shall conquer. Let the false and the fickle feel your flames."
"Your own wife begs as well, lord husband." Queen Selyse went down on both knees before the king, hands clasped as if in prayer. "Robert and Delena defiled our bed and laid a curse upon our union. This boy is the foul fruit of their fornications. Lift his shadow from my womb and I will bear you many trueborn sons, I know it." She threw her arms around his legs. "He is only one boy, born of your brother's lust and my cousin's shame."
"He is mine own blood. Stop clutching me, woman."King Stannis put a hand on her shoulder, awkwardly untangling himself from her grasp."Perhaps Robert did curse our marriage bed. He swore to me that he never meant to shame me, that he was drunk and never knew which bedchamber he entered that night. But does it matter? The boy was not at fault, whatever the truth."
"Your Grace!" Davos edged forward. "Might I speak?"
Stannis closed his mouth so hard his teeth snapped."My lord of the Rainwood. Why do you think I made you Hand, if not to speak?"The king waved a hand."Say what you will."
Warrior, make me brave. "I know little of dragons and less of gods... but the queen spoke of curses. No man is as cursed as the kinslayer, in the eyes of gods and men."
"There are no gods save R'hllor and the Other, whose name must not be spoken." Melisandre's mouth made a hard red line. "And small men curse what they cannot understand."
"I am a small man," Davos admitted, "so tell me why you need this boy Edric Storm to wake your great stone dragon, my lady." He was determined to say the boy's name as often as he could.
"Only death can pay for life, my lord. A great gift requires a great sacrifice."
"Where is the greatness in a baseborn child?"
"He has kings' blood in his veins. You have seen what even a little of that blood could do -"
"I saw you burn some leeches."
"And two false kings are dead."
"Robb Stark was murdered by Lord Walder of the Crossing, and we have heard that Balon Greyjoy fell from a bridge. Who did your leeches kill?"
"Do you doubt the power of R'hllor?"
No. Davos remembered too well the living shadow that had squirmed from out her womb that night beneath Storm's End, its black hands pressing at her thighs. I must go carefully here, or some shadow may come seeking me as well. "Even an onion smuggler knows two onions from three. You are short a king, my lady."
Stannis gave a snort of laughter."He has you there, my lady. Two is not three."
"To be sure, Your Grace. One king might die by chance, even two... but three? If Joffrey should die in the midst of all his power, surrounded by his armies and his Kingsguard, would not that show the power of the Lord at work?"
"It might."The king spoke as if he grudged each word.
"Or not." Davos did his best to hide his fear.
"Joffrey shall die," Queen Selyse declared, serene in her confidence.
"It may be that he is dead already," Ser Axell added.
Stannis looked at them with annoyance."Are you trained crows, to croak at me in turns? Enough."
"Husband, hear me -" the queen entreated.
"Why? Two is not three. Kings can count as well as smugglers. You may go."Stannis turned his back on them.
hard not to just copy/paste the entire chapters, cus Davo's chapters are some of my favorites, and I love the stannis/davos camaraderie, which is completely absent from the TV show. It's hard to imagine why Davo's is loyal at all to the Show Stannis.
