Sirius does not understand what has happened to him. He has Auror Exam #3 in the morning, a training session before that, and it's his turn to make supper tomorrow. By any line of reasoning, he should be snug in his sleeping bag of a bed on the living room floor, wishing he and James had the money to buy proper furniture.
Instead, he focuses on the feeling of the misty rain on his face as his broom speeds through the air. It's taking most of his mental energy to stay invisible against the night sky. He probably should have taken the cloak, but he didn't even think of it before he left. James probably thinks he's crazy.
He sees the cluster of lights, and he doesn't even know how he knows it's the right one. Someday, he'll get turned around and end up in Paris or something instead. He swoops down and flies through the outskirts of town until he reaches the old orange stone building. He knocks on the second window from the top, fluttering anxiously as he waits.
"Sirius?"
He can't hear Remus through the glass, but he knows that's what he's saying from the shape of his lips and the furrowing of his brows. Remus unlatches the hinge and pulls it inward.
"Hey," says Sirius softly, climbing through the window.
"I thought you had an exam in the morning," chides Remus.
"Not morning yet."
The lycanthrope rolls his eyes and opens his arms.
"Hey," Sirius repeats into the other boy's hair. "Missed you."
"Missed you too. You look exhausted." His fingers ghost over the black haired boy's cheek. "Are you taking care of yourself?"
"Course, Moony."
Remus pulls him towards the bed and begins running his slim fingers through Sirius' hair. "Someday, you'll get turned around and end up in Paris at some poor French girl's door."
"Gotta good sense of direction," protests Sirius weakly, the comfort of fingers massaging his scalp seeping into his aching muscles.
The amber eyed boy laughs, a good natured quiet melody. "Like that time you got us so lost in London that we ended up on the third floor of an art gallery instead of the park where the concert was?"
Sirius swats at him with a smile. "You like art."
Remus smiles and lies down so their foreheads touch. "I like music too."
"Want me to sing for you now?" He reaches forward and draws Remus' lips against his.
"Don't think this is exactly the time for 'The Marvelous Matilda's Men'," teases the other boy, drawing him in for another soft kiss. "Rest now, love. There's time for singing later."
"You're taking care of me again," accuses Sirius, laying his head contentedly on a human pillow of shoulder.
"Silly me," he whispers.
"I could stay here tomorrow. Send an owl that says I'm desperately ill and spend the day with you."
Remus smiles, but shakes his head. "You did that last week. You need to sleep now if you're going to slay dragons in the morning."
"Aren't you supposed to have… issues with inhumane treatment of… scaly things?" His words are starting to slur and he can't seem to keep his eyes open.
"I trust you to kill it humanely."
"Mmm," nods Sirius. "Right, then." He snuggles deeper into Remus' shoulder. "Love you, Moony."
"Love you too," he replies.
Sirius can feel Remus' invisible smile in every inch of him.
