I think d8p must be the last scum. Here's why:
1) Role mechanic - Why would Margaret Thatcher check to see if another woman was wearing makeup? This doesn't seem to make any sense
2) Margaret Thatcher is the only role who controls a large organization, and would make sense as a Godmother. I can't picture Annie Oakley skillfully managing a mafia family.
3) Inconsistent results - MeMe was "made up" yet stayed in. I was "made up" and went out.
4) Night choices - when d8p roleclaimed, he listed jeep as his Night 1 choice... If he's mafia, this would be a way to get backup for his roleclaim (and at the time, no one was suspicious of jeep). Then, he targeted only MeMe or Leo for the rest of the game. His results about Leo were weird (if he was role-blocking Leo, how was Leo stealing Cadmium's ability?), and his results about MeMe were just wrong.
5) d8p's idea for confirming himself (taken from page 14)
d8p wrote:Anyway, there is a safe way for me to prove myself here: MeMe could try to kill me tonight and I'll canvas her.
Potentially a great ploy for a Godmother.
6) Leo's results. This has already been gone into. Leo would have no bonus from calling an innocent player "guilty," except for maybe getting another kill. However, had he led the town to lynch a mafia, his credibility would've been saved.
7) 1-6, I am assuming that d8p actually is Margaret Thatcher, and is still probably scum. However, d8p has not yet been confirmed by Electra. For all we know, he could be the Bride of Satan.
