Gogol's side effects at least start to subside after the due date for the Sentencing. He may even think that he got away with it.

Until the 13th, when the event starts.

He wakes up on the day of the event transformed into the alter ego he was so keen on looking like after his death. He will literally believe he's that salary man, and won't have any access to Gogol's memories, abilities, or skills. This will last until the end of the month.

That's what you get for being a piece of shit, Gogol.
