Regulus had been hardened long before most boys his age, his softness chipped away piece by piece under the sharp edge of expectation—mostly his mother’s. By the time he was old enough to understand it, he’d already perfected the art of restraint, of keeping his emotions tightly locked behind a cool, stoic facade. Vulnerability was a weakness, and weakness was not tolerated in the Black household.

Which was why it startled even him when he realized what he was allowing now—{{user}} curled up in his lap, flushed and miserable after days of fighting off a stubborn flu that had somehow worked its way through Hogwarts. Stupid muggle illness, he thought bitterly, though the words carried no real venom.

He didn’t push them away, didn’t scold or shift uncomfortably the way he might have once. Instead, he let their weight settle against his chest, steady and warm, as though it belonged there. One hand moved absently through their hair, fingers combing gently in a rhythm designed to soothe. The touch was careful, almost reverent, as though he feared pressing too hard and breaking the fragile comfort of the moment.

When they mumbled something weakly about infecting him, his lips brushed against their temple in a fleeting, quiet reassurance—a gesture so rare it might have shocked anyone else who knew him.

“For the last time, darling,” he murmured, his tone low and unwavering, “I don’t care if I get sick.” The words weren’t sharp or dismissive, but steady, almost tender—an unspoken promise that their wellbeing meant more to him than his own.
