Why was Kath killed? I believe I have an idea.
That is an excerpt from a message to LMP. I think this post implied she was the Hunter. The wolves then killed her, knowing the Hunter is hopeless on Day 1 and that another innocent would likely be killed by her. They just got lucky with her being the Ranger.
That's what I think, anyhow.
Edit: I note that others seem to be a lot less suspicious of Saurreg than me. Check
this out.
Saurreg claims she thought Eomer was a Shirriff - and voted for him? Why? To get a Shirriff out of the way? Additionally, she said that LMP, Eomer and Kath - Three known innocents - seemed guilty.
