When Christopher arrives at Ralphie's place, Tony immediately denies killing Ralphie himself and - knowing fine well the transparency of his argument - tries to preach to Christopher, not rationally, about how much of an asshole Ralphie was.
I've always felt that scene mirrored the scene in "The Knight in White Satin Armor," where Christopher helps dispose of Richie's body.
