"I'll refrain from point out that you are serious," he said with a tiny smile. He couldn't even imagine how irritating their conversations had to be, and yet he could see that Remus loved them.
He put an elbow on the arm rest and propped his head on his hand, while he studied the other man. "You're doing it again. When you're suddenly thinking something, but only a little part of it comes out, but to answer your question, I'm pretty sure that some families have Gryffindor as default. I think that it's when you break the mould that you have to ask."
Regulus flickered his hand and cast a privacy spell. "They can go on with their drunken discussions without bothering us, and you can explain now if you like."
He still didn't understand the connection. "Sirius did something stupid and you decided to forego all relationships for the rest of your life. That makes no sense. Especially because sex doesn't have to translate into a marriage. Do you know what I think? That a Slytherin would have said 'I'll have the sex without truly trusting the other person'. You are a Gryffindor and say 'I can't have sex without the trust'. So instead of compromising like a Slytherin would do, you stop having sex and use your so called honour to hide the fact that you're scared, because like it or not, there is some trust involved. Sirius wasn't to blame, even if he was an idiot. He showed you the risks and you chose to hide when confronted with them. There are always risks. Being a werewolf only adds another dimension."
