Is That Dart?(SPOILER)
At the end of season three, a fully grown Demogorgon shows up in an end credit scene. First, is the american mentioned beforehand Hopper, or Brenner? Also, is there a chance the Demogorgon here is Dart, or D'Artagnan? Just think, he was the last demodog to "die" in season two, because of his disconnection from the Mind Flayer, and his connection to Dustin.
