When she slipped into character there was no sudden flick of the switch as there was with Jason, and no long, dramatic silences as there was with Ralph. Her transition was barely perceptible, but when she became Narcissa there was something in the eyes that told you everything you needed to know about her character: you could see the Malfoy coldness, but you could also see a softer side to her nature. I barely had to look at her and I found myself understanding something deeper about Draco.
