Whether they'd unlocked the way by reliving the emotional echoes or the plan to force the count to expend more energy making henchment loosened his hole on the magic backstage, or some crazy combination of the two, Karla and Warren were able to make their way to the wings with no pauses for dead ends, blank walls, or masked assailants. Good show.
