Gwen: John, it's good to see you. We came as quickly as we could.
John Howden: Words cannot express our gratitude, Gwen. Where is Gaius?
Merlin: I'm sorry. He was needed in Camelot but I will help in any way that I can.
John Howden: We are living in fear for our lives. We need a skilled physician, not a boy!
Sir Elyan: His name is Merlin!
Gwen: He was appointed acting physician by King Arthur himself.
