Lucrezia and Djem, "The Borgias"
Over the course of its three-season run, "The Borgias" featured a number of memorable dance sequences set at balls and weddings. But the first romantic dance of the series was a more spontaneous occurrence. In Season 1, Lucrezia was still innocent enough to not realize her feelings for Djem... until they started dancing. Sadly, he dies before the relationship can go anywhere.
Later, at Lucrezia's wedding, Cesare experience love at first sight. He falls in love with Ursula Bonadeo when the two start dancing. Somewhat later on the series, Lucrezia and Cesare's affections bubble to the surface during a dance in the Season 2 finale.
Damon and Elena, "The Vampire Diaries"
Whether you ship Delena or Stelena, fans agree that the Miss Mystic Falls dance in Season 1 was a big turning point for Elena's romantic life. When Elena gets stood up by Stefan, Damon swoops in at the Miss Mystic Falls event so Elena won't have to dance alone. Damon's feelings for Elena had been simmering for a while, but it took this dance for Elena to realize that she had feelings for him, too. Of course, it took them another season to actually act on them.
Blair and Chuck, "Gossip Girl"
