#11: Mirrored Image
It is safe to say that the season finale of season 1 was probably one of the most wonderfully bittersweet episodes we have ever seen of any show. Just when you think all is well in Will’s world, something happens that makes us realize that the whole saga is far from over.
In the last scene, a parallel is made between Twin Peaks and Stranger Things. Will coughs up a little slug, looks in the mirror, and sees lights flickering which is eerily similar to the last episode of Twin Peaks where Agent Cooper smashes his head into the bathroom mirror, effectively revealing the evil host that took over his body.
