A/N- Sansa/Margaery university AU in which they are in an established relationship and Margaery slowly meets the rest of the Starks. Too bad they're all hitting on her.

Robb, and Theon were sitting down in a corner booth at the old diner down the road from Westeros University. It was popular among students, and the two friends frequented it every Friday evening. And most Wednesdays. And for Sunday breakfast. Or whenever they ran out of clean dishes in the apartment they shared along with Jon. They were waiting for Sansa to show up with some friend she was 'Really excited for them to meet, she's so sweet, you're going to love her.'

Granted there had been a beginning to that message, but Greywind and Ghost had gotten into a play fight when Robb picked up the phone and he missed it, just catching Sansa's request for her to meet for breakfast.

"There she is!" Theon smiled, standing to greet the girl he looked at as a little sister.

The woman who followed Sansa into the diner made both boys freeze, "Is that-" Robb started.

"Margaery Tyrell." Theon finished.

"Isn't she the president of that sorority with the pink shirts."

"They're purple."

"Not important."

The boys were whispering fiercely to each other as Sansa finally caught sight of them and headed over.

Theon turned to Robb with a grin that the taller boy knew all too well. It had meant nothing but trouble for him for the last twenty six years, "I bet you I can get her number by the end of dinner."

"You're on Greyjoy." Robb smiled.

"Usual bet?"

"Loser picks up the beer for the game on Sunday." Robb confirmed.

They shook on it just as the girls drew even with the table. Robb and Theon took turns hugging Sansa, and then Margaery (Robb went for a handshake whereas Theon hugged Margaery laughing it off with a "We're huggers in the Stark family!" and ignoring Robb's "You're not actually a Stark.") before they all slid back into the booth.

"It's nice to finally meet you two, Sansa's told me so many stories about you all when you were young." Margaery smiled winningly at the boys.

"You as well." Robb replied, cutting off whatever Theon was about to say, "We've heard a ton about you too. Not too much, not like you have a reputation or anything. I just mean you're a prominent person on campus, even with the grad students." He trailed off lamely.

Theon smirked at Robb, and received a glare in return.

"Robb is getting his MBA at Westeros U. and Theon has been working for a tech start up since graduating." Sansa did the introductions shortly.

"What do you study, Margaery?" Theon asked.

"Political science and diplomacy."

"I bet you can be very convincing." He winked.

Margaery laughed politely, laying a hand on Sansa's thigh beneath the table. A move missed by Theon who was grinning smugly at Robb.

This continued on for the rest of breakfast. There was generally pleasant conversation with an undertone of Theon and Robb not so subtlety trying to hit on Margaery. They learned that Margaery's sorority was Chi Omega, and that their rush shirts were in fact baby blue. They learned Theon could bench nearly 220, and that Robb "just love family, it's so important to me to stay close with everyone- especially Sans."

Margaery barely managed to contain an eye roll as the boys continued to try and one up each other. Sansa hardly thought anything was amiss, used to the boys acting aggressively competitive around each other. Eventually the check came and Sansa made a grab for it, her hand was quickly batted away by Margaery, "Nonsense, it's my turn, you paid last time."

Theon took it from Margaery, "Allow me, it would be a pleasure to pay for you two lovely ladies." He threw the brunette another wink.

"You're two months behind on rent." Robb scoffed taking the check, "My treat, it was great getting to know you, Margaery."

Sansa beamed at how well everyone was getting along before excusing herself to the bathroom.

"It was a joy meeting the two of you, you're both so important to Sansa." Margaery smiled.

"Yeah, we should do this again." Robb agreed, seizing the opportunity, "I would love to get to know you better."

Theon jumped in, "Yeah, we should go and get drinks sometime and talk."

Margaery could take it no longer and finally decided to put the boys out of their misery, "Listen, you're both great, and I really did enjoy breakfast with you and I hope we can continue getting to know each other in the future. But I'm taken."

Robb blushed and deflated immediately but Theon was less deterred, "Is it serious?" He asked.

Robb elbowed him in the ribs, "Theon!" He whispered harshly.

"It's a valid question!"

The Tyrell laughed, "Yes I'm afraid it is serious, we've been together nearly seven months and I love them dearly."

"Damn." Theon cursed with a good natured smile on his face, "It was worth a shot."

Sansa reappeared then, and the table stood, "Ready to go?" She asked.

"All set, love." Margaery replied, shrugging on her coat.

The four made their way out of the diner, pausing at the curb. A cold breeze stirred the leaves on the ground and Sansa shivered. Margaery unwound the scarf from around her neck and looped it around Sansa, using it to pull the taller girl down to meet her lips. Margaery nipped at Sansa's lower lip, slipping her tongue into the redhead's mouth boldly before she drew back with a mischievous smile, "Let's go, darling." She threaded her fingers through Sansa's and pulled the gobsmacked girl down the sidewalk a bit towards her car, "Bye boys!" She called over her shoulder.

Theon barely managed to stammer out a choked, "Bye!" in response. Robb was too busy with his jaw on the ground. He finally managed to pull himself together enough to whisper, "My baby sister…"

Theon's shock quickly turned into amusement, "Damn! Sansa's got major game."

"She's my baby sister!" Robb practically yelled back.

"And she's consistently tapping one of the hottest asses on campus." Theon's smirk turned wolfish, and it didn't take a genius to guess what he was imagining.

Robb smacked him on the back of the head, "We don't know they're together, that could have been a friendly kiss."

"With a friendly Tyrell tongue down her throat." Theon snorted.

Robb smacked him again, "Our baby sister! She's being corrupted by that Tyrell girl!"

Theon rolled his eyes, "Three minutes ago you were imagining ways that 'Tyrell girl' could corrupt you."

Robb tried to smack his best friend a third time, but the shorter man ducked the blow and walked backwards down the sidewalk towards his car which they had used to get to the diner, "Let's go Robbie boy." He singsonged.

A/N- Jon is up next. Let me know what you thought
