"Shove over."

Dean bitched and moaned but eventually made room on the couch for his sister. Sam looked up from his laptop and smirked; Dean would make a big deal of it but they both knew that he wouldn't deny his long lost twin a thing she desired, on top of that it was Game of Thrones night and Game of Thrones night was twin night. At least it had been until last week when Hermione had found out that Cas had never seen, or even heard of, Game of Thrones. She had taken it upon herself to see to Cas' education in the subject; Sam suspected that she was proud of the fact that, in this area at least, she knew more than the millennia old angel. Hermione had decided that the quickest way to remedy the situation was to watch the marathon of the first season HBO was screening the following week, Sam had been invited to join at the same time as Cas but as Game of Thrones night tended to be the only night Sam got to himself he left them be.

"Shhh," Hermione hushed them although neither brother was talking. "It's starting!"

The sound of wings filled the air, briefly drowning out the starting sequence and Castiel appeared in front of the TV " Did I miss it?"

"No! You didn't! Now move or we will miss it and I'll have to hex you!" Hermione tended to get a bit passionate about certain forms of media. Dean had dubbed her a fangirl, in retaliation Hermione had contacted Becky and asked her to link her to some of her favourite fanfiction written by fans of Chuck's books, Hermione had then duplicated and hidden Dean's tapes before rerecording over the duplicates of her twin's music. When Dean had next gone to play his favourite AC DC tape he was instead treated to a two hour recording in which he had, in gratuitous detail, slept with and formed a relationship with Zachariah, complete with a sexy new vessel half way through. Needless to say, Dean learnt his lesson.

Cas stared blankly at the couch and Hermione sighed and shuffled over so she was leaning against Dean. The angel plopped down in the place previously inhabited by Hermione.

It was a few minutes later when Sam looked up again, he grinned to himself in anticipation as he recognized the scene, it was just before Bran discovered Jaime and Cersei in the tower, when Hermione and Dean had watched season one the first time neither had known about the existence of the other and Sam hoped to God for some sort of a reaction. Sure enough when the scene rolled around Hermione sprung away from Dean with such force that she rolled off the couch and onto the motel floor while Dean turned a delicate shade of green and groaned loudly. Sam chuckled softly, the man could kill a demon without hesitation and fight all manner of beings without batting an eyelid but ask him to watch an incestuous sex scene with his sister and you'd have him at your mercy! Dean coughed nervously and scratched the back of his neck with one hand and helping her up with the other. Hermione dusted some imaginary dust off her jeans before gesturing at the couch so that Dean would sit first. When he eventually did Hermione followed suit this time angling her body so that she was as far away from Dean as possible, with her head in Cas' lap and legs hooked over the arm of the couch. The angel looked somewhat bemused but did not protest.

Later as the end credits were rolling Cas asked a question that had obviously been on his mind for a while; " Why does the Stark family repeatedly say that 'winter is coming'? I am given to understand that winter occurs every year."

Sam glanced up again, meeting Dean's eyes, both hoping that this one sided discussion didn't last as long as some of Hermione's previous. Luckily for the Winchester boys Cas interrupted after only a minute, holding up one finger to forestall another onslaught of information, " So they say it because the seasons will last years rather than months and because there is no way of telling when winter will arrive, they repeat it to remind themselves that no matter how good it gets winter is always coming, is that correct?"

Hermione grinned, "Yeah, and also because it's their house words – kinda like their motto."

" I see," Cas was silent for a moment and then: " Demons are coming!"

In that moment Sam truly didn't know which was more terrifying; Hermione's 'Ohmygod-that-is-SO-adorable' face or the fact that Cas appeared genuinely proud of himself or that it didn't look like he was going to stop saying that anytime soon. Idly Sam wondered how long Dean would last without snapping.

Sure enough two days later, on the road to Illinois, after no cases and multiple more appropriated mottos, it happened. At the time Sam and Hermione were ribbing Dean about a very effeminate shriek that he may or may not have emitted when attacked by a particularly affectionate Great Dane.

"We do not scream."

"God DAMMIT Cas."

As Dean loudly lectured the befuddled angel on the downsides of repeating jokes too many times Hermione leaned forwards and tapped Sam's shoulder and gestured to their brother, "Does this count as screaming?"
