in the end credits scene mike puts his folder next to will yes... well..
well on noah's Instagram post titled "the end", will and dustins folders are weirdly... swapped. not saying it could be something but it could show that the duffers definitely knew what they were doing having mike put his folder next to will.
also the yellow/blue imagery here is glaringly obvious
oh, but it could be nothing because none of it means anything 😹
