Morgan told Radio Times: “A lot of my favourite stuff has been this season so far, but in past series I guess my favourite one was an episode called ‘The Last Dragonlord’, which was the finale of [Series 2]. It was an episode where we got to see Merlin for the first time confronting an element of his past.”

The actor explained: “We got to meet his father for the first time and it was the first time, I think, where Merlin got given a true element of power. He was given the gift of the Dragonlord, which was the power his father had, and it was a nice glimpse of the past.”

It was confirmed by the BBC last week that the fantasy drama will end on BBC One this Christmas.
