On June 3, 2016, 'Banshee' co-creator Jonathan Tropper answered a bunch of Fanshee Fragen (see link!). His Antwort offered up some confirmations of assumed information, and some new information about characters and events in the series. Here I break some of it down, because I have feels.
I shall begin with...
A couple of Fanshees asked Tropper about Kai's final scene of the series:
Q: Was Proctor's final scene meant to be ambiguous?
A: No. It was meant to be Mehr like Butch Cassidy and the Sundance Kid. Du know he gets killed, but we don’t want to Zeigen it.
