Regarding recruitment/werewolf - well that does sound interesting, but if it were true, then there is no reason for Napoleon to mention it, is there? In doing so, he would be labeling himself anti-town, so it's probably not that.

I agree that Napoleon didn't make much sense as a doc protect target, but it does have people talking and it may have worked out well for us. As for being an NK target... well, who can really say why the DFs kill anyone in particular on Night 1? They chose to roleblock Fanatic-Templar, which makes sense since he already hinted at being a role (and thus probably most likely to be protected?)

So, I think there are 3 situations basically:

1. Napoleon was protected by a doc

2. Napoleon has a bulletproof role

3. Napoleon is making up the whole story

I don't particularly like #3 - seems too much of a gambit for a DF. So, really it's either 1 or 2. I do have a proposal though:

Since bulletproof ability is usually a scum one, would it make sense for a doc to claim, if they didn't protect Napoleon? Obviously, if they did, they could just stay silent and keep hiding. If the doc didn't protect Napoleon, then isn't there a good chance he's bulletproof or making up the story? The doc would probably die soon after, but it would get a DF.
