Here’s an interesting final scenario.
Mark, Valerie and Steve walk down the gallows stairs shaking their head. Tom the Townie was dead. Each go to bed eyeing the others warily knowing someone’s going to wake up dead. Later that night Valerie the Vigilante sneaks out of her home at midnight and parks a few blocks away from Steve’s house. She finds an unlocked basement window and squeezes into the house. After a few hours of hiding she hears Steve get up to take a late night leak and BLAM shoots him dead. Exhuberant from her kill she returns to her car and puts the key in the ignition and BLAM is blown to bits by the bomb placed in her car’s engine by Mark the Mafioso an hour before. Mark, watching with binoculors from his bedroom window a few blocks away laughs gutterally and takes a sip of champagne to celebrate. Champagne poisoned by Steve the Serial Killer.
Three way tie, can it happen?
By the way, another thought. The doctor should only declare when he’s about to be lynched by the town, even if a Mafia is claiming Doc status. Better to remain hidden and protecting someone like the Detective then reveal yourself. While a Mafia claiming Doc status would be free from lynching for awhile eventually you’ll get lynched and then we lynch the faker. A one for one trade is in our benefit but it’s even better for us if we can keep those protections you have for a few more days.
