So, is there a reason Nanami is weak to animals? Is it some sort of zodiac thing? No, I guess elephants aren't in the zodiac. Maybe it's just karma? But it seems unconnected either to her brother or the whole duels/eternity/revolution deal.
I'm not sure why we need a detailed Nanami recap, but if we're going to have one Tsuwabuki Rosencrantz and Guildensterning himself is a fun way of doing it.
This episode does feel pretty gratuitous, but I do like the three guys singing curry and being elephants, and the silly shadow play. But maybe part of the point is comparing Nanami's relationship with her brother to Anthy's relationship with hers, which I assume will feature heavily next season?
