- The Cailleach: You are right to be afraid, Morgana. Your enemies will rue this day and all the destruction it brings, but you must beware. Tearing the veil between the worlds has created a new world, and you will not walk through it alone. The one they call Emrys will walk in your shadow. He is your destiny, and he is your doom... Emrys.
- Arthur: All the things I've faced... I never worried about dying.
- Merlin: I don't think you should now.
- Arthur: Sometimes you puzzle me.
- Merlin: You never fathomed me out?
- Arthur: No.
- Merlin: I always thought if things had been different, we'd've been good friends.
- Arthur: Yeah.
- Merlin: That's if you hadn't been such an arrogant, pompous, dollop head.
- Arthur: [Merlin is startled by the sound of a woodpecker] Merlin, you need your comfort blanket?
- Merlin: What do you mean?
- Arthur: You're making me edgy.
- [Lancelot's mount whinnies and Merlin jumps]
- Arthur: That's a horse.
- Merlin: Maybe it sensed something.
- Arthur: Yes, that you're a clot pole.
- Merlin: That's my word!
- Arthur: Yeah. And it suits you perfectly.
- Merlin: My magic is useless against them. I've tried. I have never felt so powerless. Something deep inside. And when it came for me, I felt this emptiness. I couldn't breathe. I'm scared.
