This week's AU: Soulmate!AU: Your soulmate leaves a mark on your skin in the first place they touch you.
Not The Most Subtle
Remus was laying back in bed shirtless, looking up and examining his elbow. He had trouble believing the soulmark that he saw there—both because of its particular features and… well, Remus had gone this long without a soulmark appearing to him the first time his soulmate touched him. He hadn't particularly believed that one would come his way and he was somewhat shocked. Part of him worried if he looked away it would vanish, as if the universe might realize that a mistake had been made.
Sirius interrupted his thoughts, as he so often did, by bursting unceremoniously into Remus' room.
"Do you have any toothpaste?" Sirius asked.
"You're going to brush your teeth?" Remus asked, sitting up relatively encouraged. Even if he was out of Azkaban, the weight of the Dementors still sometimes dragged Sirius through hell and made it harder for him to take care of himself. Teeth-brushing was good.
"I can do that too I suppose, but I was going to put some in those cream-filled biscuits only Snape likes before the next Order meeting," Sirius said. He leaned against the door. "What are you doing, looking at your elbow?"
"Nothing," Remus said. Sirius was one of the only people who had seen Remus bare-chested, since it was an incredibly scarred part of his body, but Remus still reached down to pull his sweater back on immediately. He didn't want to have to explain the soulmark… quite yet, anyways.
"What's on your elbow?" Sirius asked as if he was reading Remus' thoughts and being his usual contrarian self.
"Nothing," Remus said.
"No, it was…" Sirius frowned.
"Something from the full moon," Remus interrupted him.
"No, it was blue. Hang on…" Sirius crossed the room and grabbed Remus' arm, looking down at the soulmark there. "Holy fucking shit, Moony! Since when have you had this? For long? Because nothing interesting ever happens to me, and if you've been hiding this…"
"I have not," Remus said, clucking his tongue. "This is… new."
"New," Sirius said. "Like, brand new? But you haven't left the house since Monday or done anything remotely interesting other than getting a pitcher of lemonade spilled on you during the Order meeting by…"
His eyes broadened.
"No," Remus said. "No, don't say it. Don't lose your mind about this..."
"Tonks?" Sirius asked. "She touched you and gave you that soulmark?"
"No!" Remus said. As he said it the soulmark on his elbow turned from its shade of glacial blue to a bubblegum pink that… well, wasn't helping Remus' case.
Sirius looked up at him with a shit-eating grin.
"Oh, shut up," Remus huffed.
Sirius burst out laughing and the mark on Remus' elbow turned to a canary yellow colour. He ran his fingers over it and it went back to the turquoise he'd first noticed, leaving a smile on Remus' lip even as Sirius continued to laugh. He could bear his oldest friend's laughter in exchange for those gently flowing colours.
