This season saw unprecedented levels of fanservice—and we definitely don’t mean that in a bad way. The concept of a demonically possessed Stiles has existed in Teen Wolf
fandom for years, but this season made it a reality, with Dylan O’Brien taking on the dual roles of a confused and terrified Stiles, and the malevolent Nogitsune demon.
It’s unlikely that the Nogitsune storyline was directly inspired by fandom’s love of demon Stiles fanfic and GIF art. More likely, the show’s writers just recognized that Dylan O’Brien is a ridiculously good actor, and this type of storyline was an ideal way to torture every character as much as possible. But 3B also included a bunch of affectionate nods to other fanfic tropes like Stiles fighting monsters with his baseball bat, and—as we found out in the finale—the possibility that Danny knew about werewolves all along.
Best of all, the main cast are slowly but surely banding together to create the wolf pack that fans have been writing fic about since the beginning. In particular, Derek has come a long way from being an angry, distrustful jerk in Season 1, to being Scott’s biggest fan in the Season 3 finale. Seriously, that speech where he basically told both of the twins that Scott was the Best Alpha Ever? Awesome.
So yes, Season 3B did its best to satisfy the fans, neatly wrapping up the Nogitsune storyline and providing us with a central group of characters who finally work together as a team instead of switching sides every 30 seconds. But in among all of those delicious little fanservice details lurked a spectre that Teen Wolf will probably never escape: Sterek.
