As I have said, I'm Denton Walters, the Town Doctor. Flavour from my lynch actions suggests I am indeed a jailkeeper-type doctor as Rodzaju said, but I do not have enough data to be 100% sure about that. Flavour-wise, I'm pretty much the only doctor with any skill left in town, but I'm not terribly helpful these days because I'm running out of basically everything, equipment, drugs, you name it. I only want to get out of here and plan to do so the moment the lockdown is lifted.
One thing I have not told you before is this: before I claimed, I asked the mod whether I can protect myself, and was told I could. I probably would not have claimed otherwise, I don't really know. But that is what I did on the first night, which is why I quickly threw out the #460 that scared Joe so much just before nightfall; the idea was that if I were one of those killing doctors, as Rodzaju seemed to imply, I'd simply remove myself out of the game without harming any actually useful role, and I wanted to leave behind a hint in my last post to explain things if that were the case.
On night two, I protected Jefe, as I've already said. Night three I actually took the coward's way out and protected myself again, as by then I was convinced it actually was me who stopped the N2 kill and that TwilightBard and Rodzaju were going to go after me. I was blocked; I presume it was TB for the same reason, but have no proof for that.
tl;dr: Town (Paranoid) Doctor, night one protects self, night two jefequeso, night three self (blocked)
So that's it, eh? I've got an idea or two, but I want to keep them brewing for a while longer.
