In episode two, Alexander continues his journey through Iceland. He heads to Thingvellir National Park to explore a vast 40,000 mile crack in the Earth’s surface.

It feels like a sort of fetishist morris dancer costume.” Alexander hopes that Eva will go easy on him but soon finds himself being repeatedly flung to the floor.
