A second for Slavik, considered one of the greatest Latin male dancers of all time and in his prime, certainly heaps better than Stefano now (in my view ever), was hardly satisfying. I'm sure he is gracious enough to be happy for Anna, especially since her comeback wasn't that much different than Slavik's with Karina, but still. I couldn't help wondering about his feelings while judging Stefano and Anna.
As for Nino (second), did you see his face in the lineup? Funny thing is, he and Stefano practically grew up together, dancing at the same club etc.

. But maybe he was just exhausted, he actually quit doing jive several beats before the music stopped.
