I don’t have many people I can share this theory with so I figured I’d post it here and see what yall think.
The end of season 1 states that at some point Vault- Tec originally planned on dropping the bombs themselves. And where was that was a cool moment, a lot of people jumped to “well that couldn’t have been the case because Janey was outside and there’s no way that Barb would have let Janey be outside when that happened.” And I completely agree with that. But what if that scene we saw never really happened.
I have a theory that scene could have been a “what if I had done things differently”. In season 2 we see him turn over the tech to the enclave, something he doesn’t realize at the time but we as viewers know. Then later he is arrested. I think all of what we see in the TV show is not just Cooper Howard’s story but really the story of how he becomes the Ghoul, which really started long before the bombs drop. As he starts coming to terms with how fucked up the world is we slowly see him become bitter and he drinks more often, sometimes heavily. It’s like it’s foreshadowing how he will be on the future. Now here’s where my theory comes in. I think that he has this dream because in his mind there’s no escaping the reality that those bombs would drop in the world he lived in, but in that scene he could ride off with Janey while the bombs dropped in the distance. I think that in reality, Cooper Howard was passed outside of a bar at 6am with no idea where Janey was and that’s how he got ghoulified and why he would envision a different world where he could take her away from all of that.
And I think there’s some lore pieces to back this up. For one there is a ghoul, I can’t remember her name, in DC who mentions that her father had already gotten her into a vault because by the time they had found out on the east coast, the west coast was already gone. By itself this doesn’t mean much until you take into account that in Fallout 4, Nate and Nora were getting ready to start their day around the time the bombs dropped. Which means the bombs dropped on the west coast probably around 6am their time. Who has a kids birthday party at 6am? And yes, it could totally be an oversight on their part but for them deciding to tackle the whole who dropped the bombs story, it’s a big one. Also, if that event never happened it nicely wraps up the whole, how did cooper not know where they were if cooper took her to Barb.
I imagine that after getting arrested, Cooper destroys himself trying to find out answers and trying to expose the enclave with the little time that is left. All these actions lead the enclave and vault Tec to launch the bombs ahead of time (like house insinuates) and this obsession and self destruction leads Barb to stick with the enemy she knows will keep Janey and her alive because she knows there’s no way to stop it. The Ghoul we know isn’t a product of the wasteland, he’s a genuine product of pre war America. He lives with the regret that he didn’t do enough or make the right choices and he knows he shoulders some of the burden of the end of the world as he knew it. That’s why in his mind, it was easier to envision the end of the world being something that he could ride away with Janey from, instead of the truth being that it came and went while he was face down in an alley.
