Merlin: How are you, Gwen?
Gwen: I'm all right! I think. What are you doing here?
Merlin: You were injured.
Gwen: Yes, I remember now. Where's Morgana?
Merlin: She was here?
Gwen: She enchanted me. She and the Southrons and Helios plan to attack Camelot.
Merlin: They'd never succeed.
Gwen: They must know that. They have help. Agravaine gave them plans of the siege tunnels under the citadel.
Merlin: Agravaine? We must tell Arthur.
