Remus found Sirius at the top of the Astronomy Tower.
James had already told Remus not to bother, that Sirius had bit his head off when he'd tried earlier. Remus had just smiled and thanked him for the advice. Now he sat down next to Sirius, uninvited, levitating two cups of hot chocolate.
Sirius gave a low laugh, "Chocolate doesn't have the same effect on me, I'm afraid."
Remus tutted, "Well we're out of Firewhiskey so its chocolate or nothing."
Sirius took the cup wordlessly and took a sip.
Remus looked away and into the night. Fog had rolled in and removed most of the stars, only the moon remained. Their last Christmas at Hogwarts – Sirius had become more agitated since it had started getting colder, bravado attempting to hide fear.
And this would be Sirius' first Christmas without his family at all, even last year he had at least seen Regulus even if they weren't getting on.
"Elves at home always make good hot chocolate," Sirius then said gruffly, "not that that's a reason to go home obviously."
Sirius, Remus thought, was like a frightened bird, flighty if you jumped in too quick. You had to let him come to you.
"My grandma used to make amazing hot chocolate, showed me how Muggles heat it over a pan." He nudged Sirius, "we can try it over the holidays if you like."
Sirius looked over at him and Remus felt a jolt when he saw his top lip was covered in cream.
He went to wipe it off but Sirius caught his hand. "Leave it" he whispered.
He leaned over and Remus could taste the thick velvety chocolate on Sirius' lips. He slipped his tongue against Sirius' and felt himself being pulled closer. But when Sirius began to unbutton his shirt, Remus pulled back.
"We need to go back," he said leaning out to wipe the cream from Sirius' lip.
Sirius scowled petulantly, "I wish we could stay here. It's easier just the two of us."
Remus smiled and ran a hand through Sirius' hair. "Come on, hot chocolate goes cold quickly up here," he stood up and brushed himself off, "and I know James and Peter are in detention so we'll have the dorm to ourselves."
Sirius grabbed his arm and let himself be pulled up "You always make things better Moony."
"That's what boyfriends are for." Remus smirked as they walked down to the common room.
Remus may hold the key to cheering up Sirius but what James didn't know wouldn't hurt him.
