While waiting outside the wall, Baron Green had analyzed Petyr's path to power.
Duke Jon Arryn of Eyrie was himself the Defender of the Vale, influencing the Riverlands through his marriage to the Tully Family, and the Duke of Winterfell in the North was his foster son.
Duke Jon Arryn alone could directly or indirectly control the Vale, the Riverlands, and the North.
In the original show, Petyr first single-handedly orchestrated the marriage between King Joffrey and Margaery Tyrell, successfully building the Lannister and Tyrell alliance.
In return, Petyr was granted the title of Duke of Harrenhal, becoming the Governor of the Riverlands.
In the second step, Petyr informed Duke Tywin Lannister of the Tyrell's secret plan to take Sansa Stark to Highgarden and marry her to Velas Tyrell, giving Duke Tywin enough time to marry Sansa Stark to Tyrion first.
Therefore, in exchange for Duke Tywin Lannister's support, Petyr, as the Duke of Harrenhal, married Lysa Tully, bringing the Vale into his control without a single sword or arrow.
The third step was to come to the North and prepare to help Sansa Stark gain power in the North.
Petyr's route was to scheme for power in the Vale, the Riverlands, and the North.
Petyr's achievements in power overlapped with Duke Jon, so was Petyr an imitator or an admirer of Duke Jon?
...
Baron Green's voice was so calm it sent chills down one's spine: "Lord Petyr, do you like to gamble? I myself don't much care for it."
Petyr shook his head, a hint of unnaturalness in his smile.
Baron Green then said: "If someone dies in this room tonight, I bet I'll be fine, and I'll be able to return safely to Whispering City and continue to enjoy the glory of a noble."
Petyr suddenly understood why others called the Kleber Family half-savage nobles.
They were too barbaric; they simply didn't follow the rules of the game of power!
Thinking of this, Petyr's heart was not filled with alarm, but with fear.
Ha, I might die tonight!
How could he have seen through my methods? He isn't old enough to possess such ability.
Yes, Tyrion, it must be that Lannister Dwarf, Tyrion!
Petyr recalled that the attendant he sent to inform Baron Green had indeed reported seeing Tyrion and Baron Green together.
And the information about where I'm staying tonight.... Petyr secretly hated the talkative Tyrion; they were both fellows who didn't follow the rules of the game!
...
Petyr's grey-green eyes shifted: "Baron Green, I believe a great misunderstanding has arisen between us due to the slander of a petty person. In fact, I have always harbored goodwill towards you. Our alliance would be a strong combination!"
To bolster his confidence, Petyr leaned back in his chair: "You and I, we actually have a lot in common. We were meant to possess greater power."
Baron Green was unmoved, instead improvising a family motto: "The ancestors of Kleber taught me that a thousand schemes are not as good as a direct sword."
Petyr felt bitter; this barbarian wasn't listening to his good advice at all.
Leaning against the back of the chair, Baron Green crossed one leg: "Lord Petyr, I am different from you. The ancestors of Kleber, through centuries of bloodshed, forged the Kleber into a military noble, and I inherited all of this."
Petyr forced a smile.
Baron Green suddenly said: "Angai, there's a wine jug on that table, it's Arbor wine, pour us a cup."
Petyr felt an abrupt lightness; the heavy atmosphere from before vanished.
This made Petyr even more wary of the young-faced Baron Green before him.
Angai, with an innocent look, very politely and respectfully poured a cup for Baron Green and Petyr.
Baron Green raised his cup, gestured to Petyr, whose face was still a bit stiff, and took a small sip of the golden Arbor wine.
The mellow and fragrant golden Arbor wine flowing in calmed Petyr considerably: "Then, esteemed Baron Green, may I ask your purpose?"
Baron Green Lightly waved his hand: "You are a great person, I am an insignificant small person."
Baron Green stopped Petyr's unhelpful flattery, gently rubbed the wine glass with his thumb, and continued: "My ambition is too small. I have no interest in the power struggles between great people, nor do I want to get involved. There should be no conflict between us, do you understand?"
The change in Baron Green's gaze in that last moment actually made Petyr feel a chill down his spine.
Petyr nodded with a stiff face.
Baron Green rose from his chair, a gentle smile on his face: "Please forgive my abrupt visit tonight. Tomorrow morning, I still have to meet the King's Hand. Lightly advocates peace, so please help me persuade Duke Jon later."
Petyr felt Baron Green had abandoned his killing intent and finally breathed a silent sigh of relief.
Petyr, to prevent any last-minute changes, said: "As I said, we are already friends. I am very happy to help my friend, I promise."
Baron Green nodded and bid farewell: "If you don't mind, I'll use the main entrance."
Petyr's expression had returned to its usual composure and elegance. He picked up the bell by the bed and shook it.
After the bell rang, a gentle knock came from the door shortly after.
Baron Green, who had already walked a few steps, suddenly turned around, approached Petyr again, and reached out to pull open Petyr's robe. Petyr's pupils contracted, but he rationally did not move.
The dagger in Baron Green's hand flashed coldly, leaving a palm-length line across Petyr's upper chest.
The line wound left by the dagger was very shallow; Petyr didn't even feel any pain.
On Petyr's upper chest, warm blood continuously welled up along the line left by the dagger, instantly staining a large area red.
"This is the last time."
Baron Green opened the door and very calmly instructed Petyr's attendant outside to lead the way.
Petyr didn't like his attendants to be curious. Petyr's attendant, seeing no other instructions from Petyr, although puzzled, didn't dare to ask more and respectfully led Baron Green and them away.
Baron Green had been gone for a while. Petyr, who had been standing motionless, sat down, his grey-green eyes deep.
Baron Green's knife work was very skillful; it looked like a lot of blood had flowed, but the wound was actually very shallow, and the bleeding had stopped.
After Baron Green left, Petyr, who had been expressionless, showed a complex smile.
...
Early the next morning, Red Keep, near Maegor's Holdfast.
Tyrion yawned unattractively.
Jaime looked at the faintly lit sky and showed a helpless expression.
Cersei had been a bit too enthusiastic yesterday, and Jaime had expended a lot of energy. Waking up so early again by Tyrion, he was also forcing himself to stay alert.
Jaime asked: "Where did you go to play again yesterday?"
Tyrion, with half-closed eyes, said weakly: "First, I drank all night at Baron Green's mansion, then I went to Shataya's shop. Jetti, Araya, Dansi, they were really too enthusiastic, ugh, I slept less than two hours."
Jaime laughed: "After a night of revelry, you should rest well. Why did you bother to leave your soft bed and come find me so early in the morning?"
