Character Deaths that would've been great to see
Ted and Karen Wheeler- Episode 2.. Possibly the most likely to work. getting mauled by Demogorgons in episode 2 of the show would have set the stakes for incredible television and would've completely redeemed both of their characters and given Nancy and Mike a reason to fight
Robin and Vickie- Episode 6- When the demodogs are chasing Max down, they don't stop and realize that two teenagers are worth sparing. No, they brutally kill both Robin and Vickie while Lucas runs with Max's body. This would have been an Incredible way to set the stage and give a full blown shocking death for everybody to witness.
Jonathan and Nancy- Episode 6- These deaths would've impacted everything. Will's scene in Ep.7 would be better knowing Jonathan wouldn't have been there to see him finally say what he told him. Nancy would've given the Wheelers even more trauma, and we could've gotten to see Mike finally break down, knowing he is the only Wheeler still safe and sound. That scene with Jonathan and Nancy in the Goop room was incredible.....If they died
Eleven- Episode 8- Okay, so here is my vision for El's death. Dr. Kay finally catches up to her in the Upside Down. Dr. Kay gets fully killed by El. Before that however, a bullet hits Eleven, giving her a limited time to live. We get a scene with Hopper carrying Eleven's barely conscious body through the Upside Down while the vinyl song Murray has on plays in the background. Hopper won't be able to make it through in time, So Eleven gathers up all of her strength to telepathically push Hopper through the gate, saving his life and sacrificing her own without having it be too terribly forced. (This would happen after the Abyss fight, where the Military goes into the Upside Down, having them surrounded)
