Stiles shared a glance with Scott... but only once he managed to drag his eyes away from Derek. For some reason, he found the younger Derek attractive. Maybe it was a lot to do with personality, because adult Derek was more like a big brother to him who had to put up with a pain in the ass younger sibling. Derek was wanting to cut to the chase, though. Who could blame him? "More like... aged regressed," he tried to explain.

He had been going over and over in his head workable ways of trying to explain this to Derek but there was none. "Kate kidnapped you, or had you kidnapped. She took you to Mexico and whatever she did there, it regressed you back to teenage years. To before a lot of really bad crap happened to you and made you, uh... very bitter. Long story short, to us, you're usually probably late twenties. Maybe more. You've never actually told us your age or your birthday."
