At King Giles' dinner table, he's having dinner alone with Lady Helen, who asks if his son will be at the concert. She is unnaturally interested, because she's gonna kill him. King Giles is oblivious; there's even some flirting between the two of them. She asks about his dead wife, and he says that he may find love again. Go, Ripper! Just get rid of all your mirrors..
Merlin wakes up in bed, having heard the voice again, and tiptoes downstairs. Gaius is snoring, and Merlin uses magic to pull up the blankets, in possibly the cheesiest practical effect I've ever seen. Merlin crosses the courtyard and sees two knights playing dice by his destination. He makes the dice roll off the table and out the door, and the stupid guards follow them, because, hey, magic dice. Merlin steals a torch and heads for the dungeon. Wandering the hallways, he hears the creepy voice, whispering his name. Merlin comes out on a ledge in a giant underground cavern, and asks where the voice is, and a dragon swoops up, saying he's there. Collect his tears, Merlin! They turn into jellybeans!
The dragon says Merlin looks small for someone with a great destiny -- he's been given power to do great things. It seems Arthur is the once and future king, and he needs Merlin to keep him alive long enough to create Albion. Merlin says no way, if anyone wants to kill Arthur, he'll help. He calls Arthur an idiot, and the dragon tells him to change that. He flies off, and we see that he's been chained up with the world's longest chain. I guess they hadn't invented the invisible magic fence yet.
The next morning, Gaius tells Merlin to clean up his room, gather some herbs, and bring something to Morgana, for her nightmares. As he enters Morgana's room, Morgana mistakes him for Gwen, and asks him to bring her a dress as she strips behind a screen. She talks about Arthur and going to the feast, and what should she say and blah blah blah, and Merlin murmurs agreement in a high-pitched voice. Gwen comes in, and Merlin wordlessly tries to explain why he's in the chambers of a naked Morgana. Gwen apparently thinks it's adorable, and not a reason to call the captain of the guard, so he leaves without getting arrested.
Elsewhere, a serving girl brings some fruit to "Lady Helen," compliments of the king. The girl jabbers on about Helen's singing until she sees the wrinkly Mary Collins in the mirror and goes to leave in a hurry, but Helen grabs her wrist and drains the life out of her. "Helen" looks at her old-woman reflection in the mirror.
