Hey there! Due to player shenanigans, the party's stealth bunny has found their way into the enemy big bad's secret base. The session wrapped up around that point. I want to take the player into a 1 on 1 session before my group meets up again, where only he will be able to see the rolls he makes, the character chat in the text log, etc. as to keep it a surprise for when the rest of the players get there, or in case of the sneaky not making it out alive. Is there a way to do this without making an entirely different game and not having any of my maps/tokens/character sheets set up there?
