I thought they did some weird CGI stuff but that was an actual human doppelgänger. Crazy!
The whole Harvey situation is so awful, unless I am remembering how it all happened incorrectly - instead of just coming to term with his brother dying in a mining accident, Sabrina made him have to kill his brother, like he was Ol' Yeller.
Who could possibly deal with that? Even if you were a witch magic person?
