Sorry not supernatural but i need to tell this theory
You guys remember "day dream mode" that Roman can do but ONLY WITH THOMAS'S permission. So what if all side (dark or not) have a "mode" but they still need permission expect Virgil.
Stay with me here. Virgil is anxiety and anxiety comes when ever and where ever. What gives me this feeling is in Moving on part 2 we see Virgil slowly fall into himself. Maybe this is him falling into his mode. But as he has become friends with the other sides he doesn't want this to happen. So he tries to stop them and get them out.
Now going to the other part of my theory. I think I am in the small group of people that think Virgil is a dark side. He is and will always be a dark side. BBBUUUUTTT.. (haha butt) that doesn't mean he is bad. That just means he was a part of them as if they are kind of like a group. Now I think every side has a dark opposite. And Virgil is trying to cross this bridge to the good sides. And as he is getting closer to them. That is when Deceit came in to maybe try to drag him back.
Also the fact that when Deceit came in he looked at Virgil (with this "hello old pal" kinda of way) and Virgil looked back.
So what does all of these things have in common
(This is more so maybe like an au thing but still)
What if all Deceit wants is to have Virgil go full power and go full mode to get all the other dark sides. Because Deceit came up almost right after Virgil went all dark voice and heavy makeup in again Moving on part 2. That let deceit out. So what if Virgil isn't only on the bridge to the good side. HE IS THE BRIDGE TO THE DARK SIDE.. this is really silly but still had to talk about it.
Again this is mostly just shizz that us going though my mind
(Also I really want Deceit to have like a really basic name like Danny or something that would just be really funny)
(Sorry this is another side note but... I just was re re watching the sander sides. And in My NEGATIVE thinking Virgil snapped his fingers and they were out of LOGAND DREAM SPACE how did he do that if It was Logan's... this is just another thought about maybe Virgil is the most powerful side.*for now* That is all)
Love you all gals guys and nonbinary pals 😘
