I mean that your mission failing because you're on it significantly narrows down who your flavor could be, to me.
While I certainly won't suggest you watch it for this game in particular (it's an advantage but whatever), you should, it's a great show, don't listen to ash on that one. It's possibly overrated, as any geeky phenomenon tends to end up being, but still.
Well I'll give you a list. I'm not actually sure how mafia roles work right now, it could be that they just have the roles they'd normally have and maybe some stuff generically added on for balance ? I'm not sure I want to speculate publicly about what the roles might be right now anyway, though I'll give it consideration. I guess I'll give brief descriptions.
Malcolm Reynolds, the Captain, undoubtedly rank 1 right now.
Zoe (Zoey ?, whatever), the First Mate, undoubtedly rank 2 right now.
Wash, the pilot
Jayne, the muscle
Kaylee, the mechanic
That's the actual crew. Then there's
Inara, high-class escort, resident on the ship but has her own shuttle
Book, a shepherd, just travelling on the ship and happens to like it there so he stays
Then the two fugitives mentioned in the opening flavor
Simon, doctor fleeing the alliance because of
River, his sister who was experimented on and has weird psychic shit going on.
