I'm sorry that miriel doesn't want to use her role. You killed one of the other mafians meaning you're ahead as of now. That is balanced.
Look sweet heart. You don't know all the details of the roles. Godfather is immune to all kills except lynchment and is immune to investigations. That is one power role for you. Janitor can hide a role from the public. SO if you are so convinced that the town doesn't need to know of another mafia use that SECOND power role. You can day kill! Another power role. And you had a goon. So far that's 3 major power roles. Plus a goon that you communicate with so that's kinda another power role in it's own way.
Yes there is another mafia. You have figured that out. But you killed one of their power roles. As you should know if they had recruited someone they would be just a goon. And they should have a godfather as well being that they are a mafia faction. So far that's only 2 roles. Also if they had recruited someone of a power role on town side it would be null and voided as you should know. Both of you should know, del and "samus". So if they had recruited then it would just be a goon and the town would possibly be out of a power role. That leaves them possibly with one more power role.
You greatly hindered them by taking out one of their team mates. You saved your own team mate. You are above them at the moment. Work the town more if you are really bothered by it. They are sheep and you know it.
I was quite happy when I rolled you for assassin samus. Yes I thought that with kirby being the person he is that he'd take the game. But when I rolled you for assassin I thought you could stand up against him. Please don't prove me wrong honey. He would have taken this game unchallenged. You and your team are his obstacle. You being one of the last to sign up, as I was getting down to the last 3 players I was starting to get worried that the assassin role would be handed to a newer player. Take it the other one of the three wouldn't have been a bad choice either :/ I digress, you are his challenge.
