If Derek’s life were a romantic comedy—which it’s really, really not, what with all the murder, mayhem, and supernatural elements—it would inevitably feature the moment when Erica brings Stiles home and he and sees, for the first time ever, not a gawky, uncoordinated teenager with a penchant for graphic tees and plaid, but a young man, taller than Derek now, with broad shoulders and large, capable hands that finally match the rest of him. Stiles would be walking down a staircase in slow-motion and Derek would feel the world tilt on its axis while his entire perspective on life underwent a paradigm shift. Stiles would be looking at something or someone else, and he’d laugh before his gaze shifted back to Derek and when their eyes met, it would feel like being struck by lightning. Like getting hit by the thunderbolt.
