Like I said earlier, I'm Noah. My role at the start of the game wrote that I was busy at night building my Ark, and therefor could not perform any other actions. On the night of the Armageddon, I got a message that my Ark was finished. I could protect myself that night if I chose to hide in my Ark instead of attacking anyone. The message also revealed that my role was now unlocked and I had gained a new power. After the Armageddon, I could protect 2 players from being killed each night. I can even protect myself. However, I cannot protect anyone that I protected the night before. I can choose not to protect anyone, but I can't protect just 1 person. I reckon it has something to do with the Ark carrying animal-couples in the biblical story.
If you're having trouble believing me, please look back at page 56. I didn't understand how the Armageddon battles worked exactly, so I asked jnd. His response practically gave away my power to protect myself during the Armageddon, but thankfully I don't think anyone picked up on it at that point. At least I hope some scummies tried to target me and wasted a kill.

Here's the quote:

You need not worry.
I'm not the red horse or nostradamus cult or whatever crazy theory mandy comes up with next. I'm just your average friendly neighbourhood pro-town superdoctor.

By the way, revealing who I protected last night would also reveal who I can't protect next night, so don't even ask.
