If I am getting this right, people are saying that Metario give Betel the key, knowing it would be going to ravencroft.
From the chat log he posted (and of which I had at the time too), he never once mentioned that it would go to raven.
So it just seems like the nc clan is pushing the blame on Metario for giving betel the key, which betel than gave to raven, instead of betel being the one who should be in trouble here.
