Im gona bump this because it came up in my game and im a bit confused.
Is the mastermind technically in tge city? So that the bystanders would escape?
Also. Would the extra draw card happen before or after the bystander goes to the mastermind?
In my case, I drew a bystander to a blank city, and my next card was a twist.
The Mastermind is not in the city, so bystanders that he has would not escape.
The extra draw would happen after the bystander goes to the Mastermind, finish each effet before doing other.
In your case a bystander appears to an blank city, goes to the mastermind, then extra card draw, it's a scheme twist, no bystander in the city, you just do the part about your victory pile.
