The duel between Merlin and the Sidhe elder takes place shortly after the elder discovers that Merlin knows of his Sidhe-Queen plot. It starts off with the Sidhe elder, after being told by the Pixie that Merlin knows of their plans, attacking Merlin while he is sleeping. Just as the energy from the Sidhe elder's staff is about to be released and hit him, Merlin wakes up and dodges the strike. Merlin quickly retrieves his own staff, hidden under his bed. With Gaius watching in horror, Merlin then begins delivering blows, the first one missing. Eventually the energy from his Sidhe staff strikes the elder, defeating and killing him (The Changeling).
