Merlin: You don't have to continue on this journey with me, you know?
Sir Lancelot: (Chuckles) Try and stop me.
Merlin: Why? Because you're a knight, you feel honour-bound?
Sir Lancelot: You wouldn't understand. It doesn't make any sense to me either.
Sir Lancelot: I made her a vow I would keep Arthur safe.
Merlin: You don't have to worry. I'll keep him safe.
Sir Lancelot: I made a vow, Merlin.
