See a sneak peek for Saturday’s Merlin episode, entitled “The Hollow Queen.” John Shrapnel guest stars as Sarrum, and this is his introduction.

In the clip, you see Arthur and the knights greeting Sarrum and his entourage as they arrive in the castle square. You also see one of his more prominent warriors, Albin, who judging from the promotional images will pose a great threat to the King!

Sarrum announces to Arthur that he is looking forward to “testing him,” and Gwen looks on with that eerie calculating look she’s adopted lately.

We should be extra worried about Arthur’s safety this week, because not only does it seem like both Guinevere and Sarrum will be working to take him down, but Merlin will have his hands full having to help a young Druid boy named Daegal. Merlin will even have to leave Camelot, and we are left to wonder if he’ll realise what is really going on before it’s too late.

Merlin 5×08 “The Hollow Queen” airs Saturday at 20:00 GMT on BBC One.
