How does Robert Ludlum use imagery in The Bourne Ultimatum?

Imagery:

"Marie looked at her husband, his suddenly passive face outlined in the dim wash of the dashboard lights. What she saw frightened her far more than the spectre of the Jackal. She was not looking at David Webb the soft-spoken scholar. She was staring at a man they both though had disappeared from their lives forever."

"'But the hatred that obsesses Carlos grows like a cancer in his aging brain."
