He thought that whether he was right about Bones mattered very much. He was also pretty sure that while their dislike for each other had been instantaneous, their friendship for Cass kept it alive. They were like little kids fighting for Cass's attention, not even consciously, but Percy had grown up in a house with six siblings and he knew how that worked.
"Killing Lestrange had crossed my mind once or twice even before this incident," Percy said acerbically. "If you could let me know how to do that, I'd really appreciate it. You might even get a nice medal for it." He rolled his eyes. "Cass, I need something practical, something that we can use, because I don't want this to blow up in my face. It's a lot more than my life at stake here."
He moved closer and rested his fists on the mattress as he leaned toward Cass. "And I don't know how I can't believe that you never lied before and won't again. How do I know that the next time that there is a problem, you won't try something like this again? How, Cass? You keep talking, you tell me you love me, and yet, I haven't even met your mother. Bones has, though. So maybe my idea isn't so far fetched, and maybe you just like the idea of us together."
