No one supernatural can cross mountain ash. Which is fine, but as I said, that still leaves two other possibilites other than your own belief.

Which means you still can't state your belief as canon.

Dude seriously, why is this so hard to for you grasp? If there are other possibilities within the show's established canon (and there are), then something cannot be canon unless stated explicitly.

Unless you can remove all other possibilities, what you say is headcanon. And, quite frankly, even if by some miracle you do, there are always plenty of other possibilites our minds can't see at the moment.

At the end of the day, until they directly address whether or not banshees are or are not supernatural, you cannot claim to know 100%. Sorry you can't.

So, what you believe is a theory. I theory I personally think is really, really dumb.... but at least a theory I can understand the reasoning behind. However, a theory is not canon.
