Query: wasn't the black knight related to Arthur's mum?

Morganna's prophetic dream of battlefield doom visually looked like the bastard child of Game of Thrones and that Lex raining blood/sunflowers scene from Smallville. Which is appropriate for this show in so many ways.

It was so horrible I laughed out loud. I dunno, after Merlin's earlier wacky portrayal of his older self I can't take the character seriously at all.
