Christine is eating into his mind, burrowing into his unconscious.
 
Christine, blood-red, fat, and finned, is twenty. Her promise lies all in her past. Greedy and big, she is Arnie's obsession, a '58 Plymouth Fury. Broken down but not finished.
 
There is still power in her - a frightening power that leaks like sump oil, staining and corrupting. A malign power that corrodes the mind and turns ownership into Possession.
