Taking his cloak off, Remus joined the other man on the couch with a soft sigh. He wanted to boil this down to what it appeared to him on the surface -- Regulus upset because Sirius wouldn't do something Regulus didn't want to do either. But, he knew that was a knee-jerk reaction to something he didn't have the experience to truly judge.
"All right," he said at last, thinking he'd absorbed as much as he was likely to in one night. He didn't want to say the next words and he wasn't sure where the courage to say them even came from other than the resolve he'd been building not to run away from things as he had in both his past and the future. Common sense would have said to run.
Why he wasn't, he didn't know.
"What do you want to do, Regulus? Do you want to walk away? Or do you want to try this despite everything? As you say, you are young. You have time. For all we know, in a month whatever attraction is between use might have disappeared and it becomes a non-issue." What they'd do if it didn't Remus had no idea. He knew he wasn't the type who could share willingly, or even easily. But, it wasn't as if they were in love; it was certainly too soon for that. "There's time to figure out something that will make you happy and keep your family from disappearing."
What that something could be, he didn't know. But he was the optimist, after all.
