Why would anyone need to disguise a sale of ImClone stock? Kavian's having trouble differentiating between genuine evil and Martha Stewart evil. Poor Martha. She sold $250,000 of stock and is facing millions of dollars in fines and legal fees. At least she doesn't dance on the top of cars after her court hearings.
Kavian has a great many fears... perhaps he failed as a prince of the exotic country Persia. Regardless, his list of spike phobias comes from Bubba's "shrimp speech" in Forrest Gump.
