This prompt is a response to a sigilbroken on tumblr, (3/May/2014): "Joana, I have drabble prompts, if you're still taking them?! 1) Jaime x Cersei "firelight" 2) A/G "I missed you" :D" - this is the second fill, so second prompt
Gendry understood that Winterfell was part of Arya, and that they followed the Old Ways - the man who passes the sentence should swing the sword, she had told him multiple times, and she was always the one to swing the sword (even if Bran or Sansa were the ones who officially passed the sentencs - we work as a family, she told him too).
But now, she had left a fortnight ago, to deal with some rapist (or killer, he couldn't remember, probably because of the lack of sleep) in Last Hearth, and he couldn't take it anymore. Neither Ned or Allyssa could stop asking for their mother, and then their girl got sick - sure, the maester said it was nothing, but Gendry remembered being a kid and seeing children die of that in the streets of Flea Bottom.
So for now, while Allyssa was trying to get better, they were staying in one of the rooms in the castle, and Gendry couldn't help but still feel like an outsider; sharing a castle - a damn castle - with Lord Bran Stark, Lord Rickon and Lady Sansa.
For now, Gendry was trying to distract Ned, who was getting reckless of being imprisioned in this room, instead of his own, above the forge (oh… yes… there was also the problem that he was getting behind in his work), when someones knocks on the door.
"Come in," he said back, not even turning back, having not expected to be Lady Sansa, when he saw her, he immediately stood up, and bowed, paying his respects. "I'm sorry, milady."
"There's not problem, Gendry. Is Allyssa any better?"
"I think so, milady. She's cooler to the touch."
"I'm glad," she told him, before pausing for a bit and checking Allyssa for herself. "I wanted to tell you that we sighted a group of riders, it seems to be lead by Arya. You can come and wait for her in the yard with us, I'm sure I can get someone to look after Allyssa."
"Thank you, milady," he said, and with that, Sansa called the nearest maid - the baker's wife, if he wasn't wrong - to look after his girl, while he and Ned made their way to the yard.
He stood there, next to her family - I'm her family too, he thought - when she finally approached, she jumped from the horse and ran into his direction, he was ready to catch her, but she bent down and immediately picked up Ned, kissing all over his face, only then did she push Gendry into the hug, quickly kissing his lips, and whispering.
"I missed you both so much. Where's Ally?"
"She's sick…" But he didn't have time to finish the sentence, or to say he missed her too, or just for her to greet everybody, before she started running all the way inside the castle, looking for their daughter - and Gendry couldn't be more glad to have his wife home.
