The Fellowship of the Ring Werewolf

[Frank the Tank]

If it is an action, the action would be carried out regardless of a wolf or villager being lynched. The action is worded "change the lynch to guarantee a wolf is killed", the votes don't matter. It is then RNG as to who of the wolves. 

I don't fully understand this either TBQH, however, on balance of probabilities, this by itself is not a smoking gun. The balance of probability points squarely at you.

 
Yet no other ring bearer used this power until last night ?

I trust it more than your claim that all the other hobbits knew each other. And that Vincent would vote for a fellow wolf when the vote was that close last night.
