 SPOILER: Drea De Matteo (qv) and Steve Van Zandt (qv) asked  David Chase (II) (qv) to delete the scene where Christopher tells  Tony that Adriana is an informant. They felt it would be better to  keep Adrianas murder by Silvio a surprise and Chase agreed. The  scene was later used as a flashback in the episode "The Ride"  (#6.9).
