"What?" Sansa frowned.
"I'm the Three-Eyed Raven." Brandan repeated himself.
"Right. You've said that. Repeatedly." Sansa grumbled, "This is the part where you explain what it means."
"I can see the past, present and future." Brandon explained in a monotone voice.
The Stark sisters exchanged a glance, and then Arya quipped, "Oh, is that all? I was worried it would be something strange."
"Stranger than being able to put on a face and become someone else." Brandan quipped dryly, which he could see put her sisters on edge as they hadn't explained that to him yet, before he interrupted the next question, "Yes, I've seen everything you've been through. Everything. And I'm sorry, but... I see everything, and it's hard to stay me. But, of everything I've seen, the future is most tricky, because it's not fixed or easily predictable. I keep seeing things that could be, including a very dark future in which Jon and the Dragon Queen make a deal with Cersei, and she betrays them."
"Of course she does." Arya scoffed, "That's a terrible plan. Who the hell would think that was a good idea?"
"Jon would." Sansa grumbled.
"Indeed. Like father, he can be too trusting. But it's not too late. I have seen the way you two can help unite the Seven Kingdoms in an era of peace." Brandan explained.
"How?" Sansa asked.
"You must allow her to do to you, the same thing Arya has done." Brandan explained, barely acknowledging Sansa's blush, "It is the quickest way to earn her trust. Make it more likely she will listen to us. Or more accurately the two of you. But first... I have a gift for you."
Before Sansa could find enough voice to ask what it was a guard burst in and announced, "My Lady, someone at the gate is claiming to be Margaery Tyrell. We told her to leave, but she... was being very persuasive."
There was a pause and then Sansa almost tripped on her way to scurry out the room while breathlessly mumbling, "Margaery..."
The guard quickly followed her, leaving Arya to stare in disbelief, then turned to glare at her brother who reassured her in the same annoyingly disinterested tone, "It wasn't easy getting her and her brother out of the fire, or Kings Landing for that matter, but I-"
Arya honestly didn't listen to his long winded explanation, as she didn't care how this happened, she was just so angry that it had happened she could barely function. Margaery Tyrell was Sansa's first love, and Arya didn't need the competition. If Brandan knew everything he should know that. Hell, if he really was still her brother he should know that.
The Stark sisters had never liked sharing their toys, especially with each other, but now Sansa WAS Arya's toy and Arya didn't want to share her with anyone. Or at least that was what she had been thinking ever since first bedding her big sister, and for the next few minutes, before she got some more shocking information.
"What?" Arya grumbled bitterly, interrupting his story filled with mind control, "Am I supposed to share Sansa with her too?"
"Yes." Brandan said nonchalantly, earning him a look from his sister, "Trust me, it's not what I want, as I do not enjoy seeing it. But one day, you'll thank me."
"I find that hard to believe." Arya grumbled.

For the next week or so Arya continued to find it hard to believe as she watched her sister and their new guest making easy conversation, smiling, and Margaery softly touching what belonged to Arya as if she had some kind of claim on Sansa. It concocted images of the two gorgeous women in bed together, Margaery gently guiding Sansa through her first sexual experience, giving her so many firsts and in turn taking them from Arya.
Which was something Arya deeply hated, but then a new image popped into her head. One which would actually make sharing her favourite toy worth it, and one she couldn't get out of her head once it was in there. So she made arrangements to make it happen, which came to pass that night.
"My Lady." Margaery beamed as she opened the door to see Sansa, her face then dropping as she opened the door wider to find Arya sitting in a chair, just off to the side, and then she politely repeated the words to her other host, "My Lady."
"Come in, and close the door." Arya ordered.
Nodding her head Margaery quickly did as she was told and then hesitantly looked back and forth before turning to her former lover, "You wish to speak to me my Lady?"
"I'm the one who wishes to speak with you." Arya corrected, "I have an offer for you."
Margaery smiled disarmingly, "I'm all ears my Lady."
"First tell me, exactly how long were you fucking my sister." Arya asked bluntly.
There was a brief silence, then Sansa spoke up, "It's okay Margaery, this isn't a trap. Arya is gayer than Loris."
"Did I give you permission to speak?" Arya glared at her sister.
"No, sorry my Lady." Sansa quickly lowered her head in apology.
There was another brief moment of silence before Arya smirked, "This is a trap by the way, but one that you will likely enjoy."
Yet more silence, then Margaery cautiously corrected, "No one is gayer than Loris."
"We'll see about that." Arya said, deliberately cryptically, before asking, "Now answer the question. No harm will come to you. I swear."
