The worst episode in Stranger Things history could prove to be a problem for the Duffer brothers when it comes to ending the show in season 5.

I hope they don't bring the Lost Sister back. I and most fans hated that episode( S2 ep.7)
And I hope they don't play up the gay Will thing. Sure , if he's gay, fine. Don't drag Mike into it! Please! Let's keep to the original premise of the series and not get into all of that!I hope that the Duffer's will create a satisfying closure to the series.
