complete element of luck methinks. Early on I suspected laser and didnt want to give him weapons but he started to win me around as I saw he had voted for all the mafia members. luckily my unvote didnt count
for some reason I thought there was still 5 people left in the final night phase and thought I had narrowed it down to two in my own head, not realising they were actually the only two left

so that was just a bit of luck again!
