(After possessed Elyan has tried to kill Arthur twice)
Arthur: Why are you doing this?
Possessed Sir Elyan: (In the Druid boy's voice) I must avenge my death.
(They start fighting)
Arthur: What have you done to Elyan? Don't make me kill you. I don't want to kill you.
(Arthur defeats him)
Merlin: (Breaking into the room) Stop! That is not the Elyan we know!
