Marilu Henner and Derek Hough have a Viennese waltz to "Surprise Yourself." Her year is 1978, when her mother, a dancer and a dance teacher, died and Marilu got the role in "Taxi." Marilu seems much more assured this week; previous weeks have been uncomfortable to watch. At the end, the judges rush from behind the stands, Carrie Ann and Julianne hugging Marilu and Bruno hugging Derek, and, frankly, Derek deserves it for giving Marilu such a vehicle to shine. Carrie Ann says Marilu allowed herself to be great, and Julianne is happy for her — this is the routine that makes them weepy. Bruno says Marilu was brilliant.
