'Kindness' sees Morgana (Katie McGrath) step up her campaign to hunt down Emrys by capturing a familiar face, Alator (Gary Lewis) - who was last glimpsed in series four's 'The Secret Sharer'.
The reformed warlock knows the truth about Merlin (Colin Morgan) and his secret identity - will he yield under torture? It looks like time is finally running out for our hero, for Arthur (Bradley James) and for the great kingdom of Camelot...
Merlin continues on BBC One this Saturday (December 8) at 7.55pm.
