Merlin: series 4 spoilers.

Morganna's new look and info on the opening 2 parter, Revival of the Witch. I'm sure that Merlin will return with a bang seeing as it starts with a 2 parter (named above).


From What's on TV Magazine:

The series picks up one year after Morgana’s failed bid to rule Camelot and sees Arthur’s evil half-sister make the ultimate sacrifice in an attempt to regain power.
Meanwhile, Merlin is in torment after making a grave error that causes huge upset for Arthur. Guests include Nathaniel Parker as Arthur’s uncle, but is he a relative to be trusted?
