Series 5 - 6. The Dark Tower
Is snake in the grass Morgana losing her touch? To separate Queen Gwen from her protectors, the sorceress conjures up… some snakes in the grass. A little unimaginative, perhaps, but it has the desired effect, leaving Leon and Percival with dark magic coursing through their veins and Gwen in Morgana’s clutches.
A mortified King Arthur and Gwen’s brother Sir Elyan lead a rescue mission that turns into that splendidly enjoyable Merlin staple, the quest. But while Camelot’s armoured division is huffing and puffing through the Impenetrable Forest (go around!), Gwen fears for her very sanity in the Dark Tower where Morgana is keeping her.
Though the quest at times resembles a sinister pantomime, there’s nothing amusing about Gwen’s nightmarish ordeal, which makes this instalment probably the most disturbing yet. We were promised “darker” for season five — and we’ve certainly got it.
