Morgana puts a spell on Merlin

Merlin's ability for magic lands him in more hot water, when he falls into the evil Morgana's hands this evening. In her fight for supremacy, Merlin soon finds himself being used as a deadly weapon in her continuing fight. An oblivious Arthur soon finds himself in great danger, as Merlin - who's been prepared by Morgana to be the perfect assassin - is under a spell to take down the new King. Merlin's unusual behaviour is going largely unnoticed by everyone, but before he manages to do serious harm to the King, Morgana's plan is thwarted and the spell on Merlin is broken.
