Focal point

Lex relaxed considerably, though there was just something about having a finger on his forehead that could drill into his brain at any moment that didn't let him feel completely at ease. He looked at the stranger in front of him. Besides a small gap around his eyes that showed the figure was made of crystal with a blue tint in it, he was covered in wrappings from head to toe. All it would take was a pair of sunglasses and no one would ever be able to tell the figure was from the crystal race, and would mistake him for a human.

He also noticed that by commenting on the fact that he liked Lex's questions to the Kraven, he revealed that he could understand whatever language they had been speaking. Yet, the Kraven had clearly stated that his language could not be understood by inferior races. This either meant that he was lying, which was completely possible, or that the Crystal race did not fall into the category of an inferior race.
