Merlin and Sir Lancelot in “The Darkest Hour (Part Two)”

You don't have to continue on this journey with me, you know?

[Chuckles] Try and stop me.

Why? Because you're a knight, you feel honour-bound?

You wouldn't understand. It doesn't make any sense to me either.

Gwen?

I made her a vow I would keep Arthur safe.

You don't have to worry. I'll keep him safe.
