"I guessed that," he said, but there was no satisfaction. He didn't want Severus to be focused on the war, or at least not to be the driving force in his life. No one should live like that.
Regulus glared, because he wasn't so easily distracted. "Which other Potter? The one that doesn't like you and is joint at the hip with my brother, whom he married? Oh yes, I'm so worried that James will suddenly realise that he's been desperately in love with you all this time. You can see my worry, can't you?" he asked, sarcastically.
"No, Severus, the one who likes to spend his time with you, the one who looked at me like I was an inconvenience and an interference, the one who was ready to play a pissing contest with me. Granted, he's too stupid to know how much damage I could have done, but he still did it," he answered. "And whether you like it or not, you picked him, which means if he didn't think he had a claim before, he would think it now, and if you can't see all of that, then you're blind. The boy fucking wants you."
