"The space cracks there aren't the only cracks in the world," Arthur didn't buy what William just said. Even if the latter recognised the materials by linking them to the materials he saw at Lara's city, it wasn't enough to explain the look over his face when he spotted these materials.
It was the same kind of look that'd appear when someone would recognise something. Besides, Arthur was sure the materials coming out from the space cracks in the world weren't the same.
Each area would gush out different and unique sets of materials that wouldn't be found anywhere else in the world.
"First time for me to know that."
"First time for me as well to meet someone who'd recognise these materials on the spot," Arthur hinted to William that he was sure of his recognition of these materials, "all the ones protected heavily by fate and destiny aren't normal people, hahahaha!"
