"Pretending everything is normal isn't going to work."
Stiles rolls his eyes, washing the animal blood off his hands with a mildly disgusted look on his face. "I don't know. It's worked out well so far. Sure, a poor bunny or fox got in my way, but hey..." He squirts more soap onto his hands, scrubbing his arms raw. He can see Derek glaring at him. "C'mon. Better than Scott who only thought he was killing people but was actually your creepy uncle Peter. Right?"
Derek huffs, and Stiles hears the judgement before the words even fall out of Derek's mouth. "These are two completely different events."
"Well obviously." Stiles dries his hands with a wad of paper towels. "I have been a werewolf since I was a little baby. In werewolf terms, Scott's technically still a newborn."
Stiles puts his hands on the sink, head down. "Look, pretending everything is normal helps. I'm more focused, and Scott doesn't suspect a thing."
Derek moves behind him, and Stiles turns, leaning back against the sink.
"Scott also deserves to know."
Stiles narrows his eyes. "I hope you realize that nobody was ever supposed to know. You finding out was an accident, a fluke."
Derek crosses his arms. "If you won't, I will."
Stiles groans. "No, because I want to tell them on my own time."
"Stiles, you literally just said nobody was ever supposed to find out. Now, I can keep your secret because it's yours to tell. But after a week, I'm calling a meeting and telling everyone."
Stiles scoffs. "You're bluffing. You're too goody to do something like that."
Derek shrugs and holds his arms out. "Stop me."
Stiles stalks around the island, eyes dark, flashing red, and mouth pulled into a sharp smile.
"Oh I intend to."
