What if Cold Harbor actually ends up being the Battle of Cold Harbor?

Given the twists and turns and references to the Twilight Zone, if there is going to be a big twist, what if we discover we are in some bubble outside of The Civil War? I don’t know how they would do it but maybe they are trying to figure out a way to have the South actually beat the North?

The Battle of Cold Harbor is considered one of the most lopsided battles in history with high casualties. If this was Rod Serling writing the episode, he would do a twist like that so I’m wondering if we are in for a jarring twist that no one saw coming. Particularly if you think about all of the timelines of Lumon, the civil war like paintings we see, Drummond looking like he’s from the Civil War era with his hairstyle and beard 🤔

What do people think? Maybe I’m crazy but that would be a wild type of twist.
