If both Dani and Louis do an Argentina Tango, it will be interesting to watch the difference in them. Dani can probably do very precise steps and if she does it right, her acting will help set the mood of the dance. But if Louis is on good form and ready to show some emotion himself, I think he has a great presence that could really overshadow her. But that's more dependant on him putting on a show. I thought he did a bit of a smoulder with his rumba, so maybe he can do it for the AT even more.
