And just out of curiosity, I wonder what will do with other characters such as:

Sebile was Morgan's slave and companion. Sebile was that rarity, a great beauty with hair the colour of pale gold. (...) She gave birth year after year, though few of the fair-haired children ever lived and those that did Merlin sold as slaves to men who prized golden-haired children.

A slave character, but not a redhead so it's still up in the air. Excitement!
