  • For her "camp" look, Evelyne Brochu went almost completely without makeup for Episodes 4.09: The Mitigation of Competition and 4.10: From Dancing Mice to Psychopaths. Producers also thought it was time to bring back some of her infamous curls, for practical and realistic reasons and for the Cophine fans.
