Idk about Mitch now btw. Luigi as Marios mason partner makes perfect sense, and Luigi would obviously be Heroes aligned. The only way Mitch is scum is if he's lying about his character, and I'm pretty certain Odo doesn't give his scum teams full fakes, so the only other way Mitch could be scum there is if he asked N0M about his character and then faked being Luigi, which is overall a pretty unlikely scenario.
Or you know, perhaps Luigi is a scum character for whatever reason, but I'd rather expect scum to be villains like Bowser and Dr. Wily and such.
