Merlin: Agravaine is pushing for Elyan's execution.
Gaius: Arthur may have no choice but to sentence Elyan to death.
Merlin: We can't allow that to happen.
Gaius: What do you propose we do, Merlin?
Merlin: There must be a way of ridding Elyan of the spirit that possesses him.
Gaius: It would require very powerful magic.
Merlin: Then I must master it if I am to save Elyan's life.
Gaius: And you intend to expel the spirit in the cells, under the noses of the guards?
Merlin: Of course not. First we need to break Elyan out of the cells. Did I miss out that part?
(Gaius laughs nervously)
