Welp, I learned Mat's role last night, and let the record know... I am disappoint.
So... let me start by saying:
IT'S ALL THERE, BLACK AND WHITE; CLEAR AS CRYSTAL!
You had the power to switch roles with someone, WITH THE OTHER PERSON NOT KNOWING YOU DID IT! Plus, the other mafia members didn't know who you were; you were anonymous in mafia meetings, EVEN AFTER THE SWITCH! Do you not realize the power you had the ENTIRE GAME!??! You, sir, had the most awesome role out of everyone here, and you never even used it. You've had so many opportunities to not only screw over the mafia, but to make a difference in this game. Instead, you chose to sit in a corner, your thumb up your ass, and simply wait; unnecessarily endangering yourself while in possession of the most awesome power in the game. You did nothing, therefore you get NOTHING!
YOU LOSE! GOOD DAY, SIR!
