Grey was the color of Lex's world. He existed in a cloud of the indecisive shade. Not pure white but not quite the inky darkness of black. His inner battle surfaced in the color gray. The longing for friends and family, for Clark's life warred with the impulse to snatch out and take what he wanted. His inner child screamed in psychotic rage that Clark was always forgiven, that Clark always got everything Lex wanted.
Including Chloe Sullivan.
Lex watched Clark standing outside Chloe's room and his silent encounter with a glowering Lana made sense. Clark was a precipitating factor in Chloe's condition. Mrs. Kent placed an arm around her son as she left Chloe's room. Lex felt a muscle in his jaw jump. Even when the world tumbled around him, Clark still lived in the white light.
Lex turned and left, calling his florist on his cell as he did. He ordered white roses to be sent to Chloe's bed side.
When she recovered, she would be a possibility to extract information from Clark. Lex was unsure if that would involve her participation or merely using her to blackmail her former lover.
The color of Lex's world darken a little.
Grey was the color of Lex's descent.
