S4-E4 Aithusa



onight’s guest actor, James Callis, must have suffered an identity crisis during filming. Not only did he take the lead in a 2010 TV movie about Merlin but also, in the matchless sci-fi saga Battlestar Galactica, he played a character called Gaius.

His chief role here is to come between Merlin’s Merlin and Merlin’s Gaius — as Julius Borden, a visitor to Camelot intent on finding the last remaining dragon’s egg. Merlin, a Dragonlord don’t forget, is only too keen to assist, but the ever suspicious Gaius has issues with the interloper…

It’s a hearty broth of a story, with a stirring, widescreen quest, gigglesome asides (some trousers-down tomfoolery and a bit of shameless subterfuge worthy of Basil Fawlty), a lovely, unspoken ice-breaker between Merlin and his mentor, and a story arc that hits the spot — younger viewers will adore the ending.


A mysterious stranger arrives in Camelot claiming to have located the final part of a key to a tomb containing the last remaining dragon's egg. Merlin is intrigued and promises to help him - but the man's motives are soon called into question. Colin Morgan and James Callis (Battlestar Galactica) star.
