I had just assumed it was a knight helping Merlin dodge a Dorocha. Looking at the scenery and the lighting, it certainly doesn't look like the area where the Cailleach was. I think it was just in Daobeth, but I could be wrong. I also noticed the scene with Morgana riding on the horse in the trailer, after she said "we're going on a hunt", and in the trailer it was sunny, and her eyes didn't glow gold, so they put in footage that wasn't as highly edited to give a different impression of the scene.
