1st September 1971

Sirius smiles faintly at his younger brother, the two of them separated by the window of the Hogwarts Express. For a moment, all of the excitement that had been bouncing around in his stomach suddenly compressed into a weighted ball of anxiety. Hogwarts was going to be a fun, new adventure, you had reassured him of such that morning, however, seeing Regulus looking up at him through the window made his stomach drop into an unknown abyss.

"Take care, Siri," Regulus smiles toothily, having to tilt his chin up to see his older brother better. He didn't want to forget a single detail about how his brother looked. It was an unreasonable fear but Regulus was scared stiff over forgetting a single thing about his older brother.

"'Course! You take care too, Reg," Sirius looks up at you for a moment but you don't meet his eyes, seemingly distracted by something that catches your eye in the crowd, "I know Mother is different now but I'm worried about you..."

Shocked by his brother's concern, Regulus feels a small urge to look over his shoulder and observe you in the hopes that the swelling of apprehension in his stomach can settle, somewhat. It's easy to trust you now but it's also just as easy to fall back on being guarded, for his own self-protection — with Sirius gone, his only brother, who often acts as his shield and protector, fear is one stray, all-consuming thought away from devouring them both. They've never been without the other for any extended period of time. This was going to be a first.

"I know..." Regulus nervously tugs on the hem of his sleeves, trying to ground himself with the action, "but I don't think she'll change back... and besides, I have Kreacher," Sirius' lips pull into a thin line. Yes, he's started getting along with the house elf a lot better recently, mainly due to Regulus and his mother's influence but Sirius knows the truth. If Kreacher was ever forced to choose between Regulus and his mother, Kreacher would pick you, the Matriarch of the Black family. His little brother is too naive and soft-hearted for his own good.

"Write to me if anything goes wrong, okay?" Regulus only nods before they silently decide to let go of the tense subject and, at least, part on a lighter note, "I promise I'll write to you about everything that happens, I won't miss a single detail!" the two grin at each other, "By the time I come back, you'll be an expert about Hogwarts and you won't be fumbling around and making mistakes like me on your first year,"

A sharp whistle tears through the air and the brothers share a tearful look before Regulus rushes back to cling onto your skirt, the both of you keeping your eyes solely on Sirius whose heart can't stop clenching — in distress or excitement, he cannot fathom what the emotion behind it all is. In the distance, he watches his mother's lips move to form the words 'I love you'. It's like she's whispering it to him, loving and kind and full of warmth, like the wonderful mother she's suddenly become. Just one month... he wishes you had been whispering that endearment to him for longer than that.

Despite his worries about what may happen to Regulus in his absence, Sirius meets your eyes with a smile and whispers an 'I love you' back. Deep in his chest, his heart settles in content, happy and blissfully optimistic over your disposition. Your eyes hold such bountiful amounts of love, that he feels slightly ashamed for thinking the worst of you. There's no way you would dare lay a hand on Regulus the way you used to, in a cruel means to elicit 'appropriate' behaviour. Not when you adored cuddling him so much, not when you adored pressing soft kisses into his head of curls, not when you catered to his preferences for every meal ever since that fateful day, and especially not when you would always be the first to step in between him and their father during every irate spat.
