Yawn. Good morning folks!
Flounder no longer! Last night, I discovered a prime lynch target, and I believe we should 
Lynch THE_IRON_KENYAN. 
Here's why!
Now, notice that he claimed to know of all the other Rohirrim. This directly goes against the idea of the game, that the village is an uninformed majority!
Taking the game OP too literally. Weaksauce argument 
Furthermore, in a later conversation, I tried to verify the veracity of his claims - whihc is to say, I put some names to him. Some were Rohirrim, some weren't. He said they were all false.
Naturally, my alarm bells blazed. Now, I'll tell you what I think TIK is right now. Note that, where possible, it could be a combination.
- High
 
- Confused
 
- A neutral who has knowledge of all the Rohirrim and moles them to high heaven
 
- A Sauronite who has knowledge of all the Rohirrim and moles them to high heaven
 
What about this option: I only know some of the other rohirrim, and it turns out there are more of them or this other option:
You are lying and there are no other rohirrim besides the rohirrim I know
I rest my case. Bandwagon away!
