"Little Mockingbirds": The Agents/Supporters of Littlefinger (Spoilers Extended)

"You could turn King's Landing upside down and not find a single man with a mockingbird sewn over his heart, but that does not mean I am friendless."

Background

Varys has his little birds/mice that "provided to him" without tongues as well as numerous other characters/disguises. In this post I thought it would be interesting to look into another major player in the game (Petyr Baelish) and the different characters that are working for him/loyal to him (at some point or another).

Note: LF has obviously collaborated with major characters/groups previously (like the Tyrells in the Joffrey assassination plot) but they don't work for him/or owe him anything

The Vale/Arryn Household

• Ser Mandon Moore

While not 100% confirmed (others argue for Joffrey/Cersei, but I think the evidence points to LF most), Ser Mandon Moore is killed by Podrick after trying to kill Tyrion on the Blackwater.

• Ser Hugh of the Vale

• Pregnant Serving Girl/Stablehand/Potboy

I would argue there is less evidence for Ser Hugh than Mandon, but it is worth noting that these are the characters that LF freely gives to Ned as options (that will in turn Ned will send someone to and Varys/the Lannisters will notice):

Littlefinger smiled. "I promised Cat I would help you in your inquiries, and so I have."That took Ned aback. Promise or no promise, he could not find it in him to trust Lord Petyr Baelish, who struck him as too clever by half. "You have something for me?"

"Someone," Littlefinger corrected. "Four someones, if truth be told. Had you thought to question the Hand's servants?"

Ned frowned. “Would that I could. Lady Arryn took her household back to the Eyrie.” Lysa had done him no favor in that regard. All those who had stood closest to her husband had gone with her when she fled: Jon’s maester, his steward, the captain of his guard, his knights and retainers.
“Most of her household,” Littlefinger said, “not all. A few remain. A pregnant kitchen girl hastily wed to one of Lord Renly’s grooms, a stablehand who joined the City Watch, a potboy discharged from service for theft, and Lord Arryn’s squire.”

“His squire?” Ned was pleasantly surprised. A man’s squire often knew a great deal of his comings and goings.
“Ser Hugh of the Vale,” Littlefinger named him. “The king knighted the boy after Lord Arryn’s death.”

Since the topic is LF's agents, I think the below scene is worth noting. Not only because it continues upon the above passage, but also because of what he is showing Ned. Also the show takes it a step further and has him show Ned someone who is also one of LF's agents:

“I shall send for him,” Ned said. “And the others.”
Littlefinger winced. “My lord, step over here to the window, if you would be so kind.”
“Why?”
“Come, and I’ll show you, my lord.”
Frowning, Ned crossed to the window. Petyr Baelish made a casual gesture. “There, across the yard, at the door of the armory, do you see the boy squatting by the steps honing a sword with an oilstone?”
“What of him?”
“He reports to Varys. The Spider has taken a great interest in you and all your doings.” He shifted in the window seat. “Now glance at the wall. Farther west, above the stables. The guardsman leaning on the ramparts?”
Ned saw the man. “Another of the eunuch’s whisperers?”
“No, this one belongs to the queen. Notice that he enjoys a fine view of the door to this tower, the better to note who calls on you. There are others, many unknown even to me. The Red Keep is full of eyes. Why do you think I hid Cat in a brothel?”
Eddard Stark had no taste for these intrigues. “Seven hells,” he swore. It did seem as though the man on the walls was watching him. Suddenly uncomfortable, Ned moved away from the window. “Is everyone someone’s informer in this cursed city?”
“Scarcely,” said Littlefinger. He counted on the fingers on his hand. “Why, there’s me, you, the king … although, come to think on it, the king tells the queen much too much, and I’m less than certain about you.” He stood up. “Is there a man in your service that you trust utterly and completely?”

Yes,” said Ned.
“In that case, I have a delightful palace in Valyria that I would dearly love to sell you,” Littlefinger said with a mocking smile. “The wiser answer was no, my lord, but be that as it may. Send this paragon of yours to Ser Hugh and the others. Your own comings and goings will be noted, but even Varys the Spider cannot watch every man in your service every hour of the day.” He started for the door.
“Lord Petyr,” Ned called after him. “I … am grateful for your help. Perhaps I was wrong to distrust you.”
Littlefinger fingered his small pointed beard. “You are slow to learn, Lord Eddard. Distrusting me was the wisest thing you’ve done since you climbed down off your horse.” -AGOT, Eddard V

Drearfort Retainers

• Bryen (Captain of the Guard)
• Kella (Shepherd)
• Grisel (Former Wet Nurse/Keeper of the Drearfort)
• Umfred (Steward)
• Old Blind Dog

At Littlefinger's keep, there are several servants as well:

"Nothing says home like the smell of burning dung." Petyr turned to Sansa. "Grisel was my wet nurse, but she keeps my castle now. Umfred's my steward, and Bryen—didn't I name you captain of the guard the last time I was here?"
...
"And very well, I'm sure. No one has made off with any of my rocks or sheep pellets, I see that plainly." Petyr gestured toward the fat woman. "Kella minds my vast herds. How many sheep do I have at present, Kella?
"She had to think a moment. "Three and twenty, m'lord. There was nine and twenty, but Bryen's dogs killed one and we butchered some others and salted down the meat." -ASOS, Sansa VI

There are also dogs, sheep and several of Kella's bastards.

Hired Swords

While Littlefinger doesn't have armies and lords loyal to him, it should be noted that he does seemingly have some men. At least enough that were willing to join in on this (this is treason if you're caught):

Sansa raised a hand to her mouth. "You cannot mean . . . she wanted to take me to Highgarden, to marry me to her grandson . . ."
"Gentle, pious, good-hearted Willas Tyrell. Be grateful you were spared, he would have bored you spitless. The old woman is not boring, though, I'll grant her that. A fearsome old harridan, and not near as frail as she pretends. When I came to Highgarden to dicker for Margaery's hand, she let her lord son bluster while she asked pointed questions about Joffrey's nature. I praised him to the skies, to be sure . . . whilst my men spread disturbing tales amongst Lord Tyrell's servants. That is how the game is played.
"I also planted the notion of Ser Loras taking the white. Not that I suggested it, that would have been too crude. But men in my party supplied grisly tales about how the mob had killed Ser Preston Greenfield and raped the Lady Lollys, and slipped a few silvers to Lord Tyrell's army of singers to sing of Ryam Redwyne, Serwyn of the Mirror Shield, and Prince Aemon the Dragonknight. A harp can be as dangerous as a sword, in the right hands. -ASOS, Sansa, VI

• Ser Dontos Hollard

The sword loyal to LF that we meet is Dontos Hollard who helps Sansa escape the Red Keep:

He did that for me. I thought it was Ser Dontos, my poor old drunken Florian, but it was Petyr all the while. Littlefinger was only a mask he had to wear. Only sometimes Sansa found it hard to tell where the man ended and the mask began. Littlefinger and Lord Petyr looked so very much alike.

before he was killed once he was no longer needed:

"Lord Petyr," Dontos called from the boat. "I must needs row back, before they think to look for me.

Petyr Baelish put a hand on the rail. "But first you'll want your payment. Ten thousand dragons was it?"
"Ten thousand." Dontos rubbed his mouth with the back of his hand. "As you promised my lord."
"Ser Lothor, the reward."
Lothor Brune dipped his torch. Three men stepped to the gunwale, raised crossbows, fired. One bolt took Dontos in the chest as he looked up, punching through the left crown on his surcoat. The others ripped into throat and belly. It happened so quickly neither Dontos nor Sansa had time to cry out. When it was done, Lothor Brune tossed the torch down on top of the corpse. The little boat was blazing fiercely as the galley moved away. -ACOK, Sansa III

• Oswell Kettleblack
• Ser Lothor Brune

I never asked to play. The game was too dangerous. One slip and I am dead. "Oswell . . . my lord, Oswell rowed me from King's Landing the night that I escaped. He must know who I am."
"If he's half as clever as a sheep pellet, you would think so. Ser Lothor knows as well. But Oswell has been in my service a long time, and Brune is close-mouthed by nature. Kettleblack watches Brune for me, and Brune watches Kettleblack. Trust no one, I once told Eddard Stark, but he would not listen. You are Alayne, and you must be Alayne all the time." He put two fingers on her left breast. "Even here. In your heart. Can you do that? Can you be my daughter in your heart -AFFC, Sansa I

• The Kettleblack Brothers (Osmund/Osney/Osfryd)

Obviously their loyalty is dubious but it is worth noting:

The black amethysts. "But . . . if not Dontos, who? Do you have other . . . pieces?"

"You could turn King's Landing upside down and not find a single man with a mockingbird sewn over his heart, but that does not mean I am friendless." Petyr went to the steps. "Oswell, come up here and let the Lady Sansa have a look at you."

...

Oswell grinned, showing a mouth of crooked teeth. "No, but m'lady might of met my three sons."
It was the "three sons," and that smile too. "Kettleblack!" Sansa's eyes went wide. "You're a Kettleblack!"
"Aye, m'lady, as it please you."

• The Mad Mouse/Byron the Beautiful/Morgarth the Merry

Something that Oswell learned from the Merling King led Littlefinger to hire more swords:

"Hungry knights. I thought it best that we have a few more swords about us. The times grow ever more interesting, my sweet, and when the times are interesting you can never have too many swords. The Merling King's returned to Gulltown, and old Oswell had some tales to tell."

She knew better than to ask what sort of tales. If Petyr had wanted her to know, he would have told her -AFFC, Alayne II

• Ser Lyn Corbray

The venom in his voice was so thick that for a moment she almost forgot that Lyn Corbray was actually her father’s catspaw, bought and paid for. Or was he? Perhaps, instead of being Petyr’s man pretending to be Petyr’s foe, he was actually his foe pretending to be his man pretending to be his foe.

Just thinking about it was enough to make her head spin. -TWOW, Alayne I

The Lords Declarant

• Benedar Belmore
• Symond Templeton
• Anya Waynwood

While I wouldn't consider any of them officially in his employ, it is worth noting that all 3 of these characters attend Lyonel Corbray's wedding in Gulltown.

If interested: The Lords Declarant

Other Vale Lords

• Lyonel Corbray
• Nestor Royce

Not a member of the Lords Declarant, but Nestor Royce owes his new title (House Royce of the Gates of the Moon) to Littlefinger.

TLDR: Just a list of characters who have been agents of LF at some point (some allegiances have changed).
