Anand's seconds and Carlsen's funny reaction

Nov 7, 2013, 8:20 AM |

In the link from the press conference bellow scroll to 8:38:40 of the press conference video (the bottom video, not the top from the opening ceremony).

You see Magnus Carlsen's reaction to Anand's announcement that Peter Leko is his second. It is quite funny but I am not sure what it means. Is he surprised or he simply does not believe him? Two minutes later 8:40:45, Anand implies that he could be lying. Everybody is reporting that Anand's second is Peter Leko but is that true? And why are there secret seconds in the first place? Anybody knows?
