Scott and Stiles are hanging out in Stiles's room one night when Derek Hale appears through the window. He doesn't exchange any pleasantries, and just gets right to the point. "Have either of you two seen Isaac lately?" He demanded, his voice in his usual no-nonsense growl. "What do you mean?" Scott asked as he sat up from his reclined position on Stiles's bed. "Yeah, like when? During school? Cause I don't know if you've noticed or not Derek, but Isaac's considered a fugitive now, and fugitives don't exactly show up to high school English class." Stiles added sarcastically from his spot over in front of his computer at his desk. After a cold glare shot in Stiles's direction, Derek continued. "Isaac keeps running off for periods of time without any explanation. It's normal for him to do whatever he wants, but there's something weird going on. I'm about to go out and track him, but I thought I'd better check to make sure you two didn't have anything to do with it." "No," Scott replied earnestly, "Every time we've seen Isaac he's been with you." "Do you have any idea where he could be going?" Stiles inquired. "That's where you two come in." Derek said, pointing at the both of them before crossing his arms, "I want you two to find him." "Whoa, whoa, whoa. What do we look like, the Hardy Boys? Going out to solve the mystery of the disappearing werewolf teenager? I don't think so-" Stiles began before Scott cut in. "We'll do it." "Good," Derek said, headed for the window, straddling the sill, half way out and half way in Stiles's room when he turned back to add, "I'd say don't get into any trouble, but given your guys' history, I'd be wasting my breath." With that snide comment he was gone, vanishing into the night to do who knows what. "He acts like we go looking for trouble!" Stiles exclaimed, exasperated. Scott gives him a slow look. "What? We go out and happen to always land in troublesome situations, it's a completely different thing." Stiles muttered as he went back to his computer. Scott looked out the window where Derek had been moments before. "I wonder where Isaac's been going." Stiles swiveled around, face serious. "I don't know...I mean, where does Isaac go all the time? As I already mentioned, he doesn't have school to kill most of his time during the day like we do." "Exactly." Scott nodded, "Derek even said he lets Isaac run free most of the time, and he probably doesn't even know where he goes then. So for Derek to actually be concerned on Isaac's whereabouts, Isaac would have to seem pretty suspicious for Derek." "If we let go of the fact that Derek is naturally suspicious and untrusting towards everyone he has ever encountered in his life and chalk it up as one of his many wonderful charming personality traits, yeah, you're right." Stiles remarked. "And isn't it a little odd for Derek to come check with us first on anything? Like, since when does the big bad Alpha wolf need to check with us before acting?" Scott thought for a moment before replying, "I think he did want to know if we were involved, and then decided he could use our help." He looked out the window again. "He may have tried to not show it, but Derek's worried about Isaac." "Because of his development as a werewolf since the bite?" Stiles ventured. "Yeah," Scott said still lost in thought. "Either way, tomorrow we need to track Isaac down and find out where he's been going."
