What if Fyodor possessed Sigma wouldn't that be crazy hahah

So with the Jesus allegory from the last episode he doesn't get completely reincarnated, but a copy of himself is made within Sigma from the information transfer, and it's almost like he's reincarnated.

OK hear me out

I don't think this is actually what's going to happen with the anime, but I DO think this plot is plausible enough that it could happen in one of bsd's many canon alternate timelines.

So you know how Fyodor did the whole 'help me I'm innocent and the real Fyodor has taken over my body 🥺' stchick to trick Sigma? OK so in this scenario let's say that's actually foreshadowing.

Fyodor's ability, although I'm not exactly sure what it is, based on theories seems to involve him being able to make another version of himself. Some people even believe he can put a version of himself inside of someone to kill them from the inside (I don't have the exact reasoning but there are theories just go with it).

After Sigma uses his ability on Fyodor to gain EVERY one of Fyodor's secrets and everything about him, he passes out from information overload as we know. What if in this coma state, Sigma and Fyodor's abilities are combining (Sigma gaining all of Fyodor's knowledge, Fyodor putting a version of himself inside of Sigma), and this creates a version of Fyodor created just from the knowledge Sigma gained of him. This version takes over the body, and when 'Sigma' wakes up its actually a new version of Fyodor (especially because Fyodor would be made of more knowledge than Sigma considering their lifespans, so Fyodor's consciousness could be more powerful).

So it's not like a ghost possession situation, it's an ability possession similar to what happened with Shibusawa.

So 'Sigma' walks out of Mersault, maybe during whatever chaos happens in the 2 hours, and sees Nikolai still holding the original Fyodor's arm.

Nikolai is shocked to see Sigma alive and awake, but then soon finds out that it's actually Fyodor (or a copy of him) in Sigma's body. Fyodor doesn't know about any events that happened before the information transfer, so he doesn't know about Dazai getting shot, Chuuya and Dazai's plan, or his original self dying. So Nikolai fills him in on that.

At that point, Fyodor realises he'll need to stay underground again for some time before he can get back at Dazai and continue his mission. It's helpful though that everyone believes he's dead and that he looks different, since people won't be looking for him.

So Fyodor and Nikolai go underground together this time, because with the DOA now in shambles Nikolai is Fyodor's only ally. And Sigma is currently trapped in his body, but in a limbo between consciousness and unconsciousness. His own conscious is in his body being relayed information over and over to keep him in an overloaded state.

Also for this AU Fyolai are still repressed homosexuals (Nikolai a little less after his post Fyodor death speech but still repressed enough), because even if I'm putting Sigma through a body possession plot I'm not gonna have his body be in the middle of Fyolai kissing I wouldn't do that to him.

Fyodor intends to find a way to get a body for himself, and they bring along Fyodor's arm and find a way to attach it to him again as a start (I thought about a Mary Shelley character having an ability to do this, but I forgot she already exists so I'm still thinking about how they'd do this).

I can also imagine Fyodor using Sigma's appearance to fuck with Dazai as a part of his plan later on. Maybe he takes more of his acting classes and even pretends to be Sigma at some point in the future.
