Fake roles

I need a good fake role. Hsu can claim to be a citizen if it comes down to it but I already said I had a role. I'm thinking it's not wise to claim weak doctor at all now, especially since less people left in the game and so few of us. I was going to say it because I thought I was going out early and it'd buy me a couple days but I might be staying in until close to the end after all.

Best bet might be to make up one and say Del and Miriel made it up. Any ideas?

I'll look over actual existing roles and see if there's one I can pick from there too later.
