Fix It: Vincent!
So.
Post theatre.
Vincent wakes up however long it has been in the past. "There's another reason why I'm on my knees right now." Is still ringing in his ears.
He is screaming, crying, throwing up, locking himself in his room and refusing to come out. Chisha is having a panic attack because of how worried he is.
Three hours later, a very haggard looking Vincent comes out with a drawing and a very long letter.
The drawing is of Subaru. The letter is for Subaru.
He makes sure to give Cecilus the drawing and a long distance communication mirror and the instructions of 'Don't let Subaru die.' This way he can get regular updates on what is happening with Subaru while making sure that she doesn't die while he's not looking.
The letter is mostly a guide to Lugunican social norms and basic history, with a few tips on how to avoid very specific deaths along the way. The rest of the letter is him explaining that there is magic to transform one's body into the opposite sex if Subaru is interested.
Vincent would love to kidnap Subaru to Vollachia, but first needs to Subaru-proof the entire country and prepare for the Great Disaster.
Vincent also very busy trying to figure out how to make sure neither he or Chisha dies in the Great Disaster, and also planning their wedding. Which Subaru is invited to. She'll probably end up attending as Cecilus's plus-one or something.
Eventually he'll have Subaru be moved to the Empire permanently, there is just so much that needs doing first.
Cecilus is about to have the best holiday of their life while the entirety of Lugunica is going to experience the nightmare of Subaru's very enthusiastic pet Divine General.
