While a drunken four classed wonder-PC was charming the pants off of a disguised kobold at the opera, the rogue managed to sneak in the back and disguise himself as part of the acting troupe. Unfortunately, through just lack of attention to the scenario or just some absentmindedness, he didn't realize that the Chelish play he was an extra in might have him being stabbed during the play. It was funny to have him play "odd-number out" with some NPCs (he cheated) whilest not realizing why he was doing it until the guy next to him got stabbed on stage. Pretty funny reaction from the player!
Also, I went 10 rounds as the boss at the end. Who knew illusions were so useful ...?
