Twitter is a wonderful resource. Over the last few days we’ve gotten pictures from dancers of Derek filming at their dance rehearsals or events. Lena and Elara had sharp eyes and noticed a hashtag on one of the photos that read #tvpilot. That, in addition to another tweet that referenced Derek and Julianne’s show, and I think we might have our answer. I think Rose, in the comments on Part 1, is likely right.
