Thanks to an anonymous source we are proud to be able to bring you a scene description from Merlin, series IV!
Lancelot: You shouldn't be here, Merlin. You have no powers.
Merlin: (walking nearby, gathering firewood) It doesn't matter.
Lancelot: You're not a warrior, Merlin. I don't want to see you die.
(Some dialogue missing here)
Lancelot: We leave in the morning.
-In another scene Merlin and Lancelot (this time in his Camelot cloak) ride through the woods. Merlin bends over in his saddle looking in pain, and Lancelot offers him something (it seemed to be a drink).
-In yet another scene, Merlin and Lancelot ride together. Merlin was using the last of his energy to tell Lancelot something, before he apparently collapses to the floor, unconscious.
