[the phantom]

I see no reason to do a special Seer-test plan. Remember, the Seer is not just being told innocence/guilt, but the actual role! It won't take long at all for the Seer to figure out if the dreams are right, and there's no reason to set up a special kill for it, especially if you believe that you are purposefully letting someone furry live an extra day in order to have a test subject. Plus, the business that it wouldn't be proper to off him because he's gone? If you think about it, your plan is much more cruel, as you're basically deciding, "We're going to wait for Nog to come back and then lynch him. That way he has all day to experience the frustration as he kicks and thrashes in vain."
