Merlin: Do you really think I can do this, Gaius?
Gaius: I know you can.
Merlin: But I'm not a Physician. I don't have the knowledge you do.
Gaius: You've been working with me for many years. I suspect you know more than you think.
Merlin: I just do what you tell me to do, I don't have to make the decisions myself. These people will be putting their lives in my hands.
Gaius: I put my life in your hands every day, Merlin. As does Arthur and Gwen and all of Camelot, though they may not know it. You are the one who holds the fate of this kingdom in the balance.
Merlin: That's different. That doesn't require a lifetime of learning, just...
Gaius: Intelligence? Courage? Compassion? All I know is I have every faith in you.
