Yeap, at first I thought "Brother kills Brother" mean Arthur kills Morgana but then I automatically realised Morgana is a sister.

So, that will be a huge surprise to us. Perhaps, an alternative twist ? A brother for Mordred or Melrin?

Or could Arthur be Mordred's brother? No, he couldn't but that's a funny theory.
