Egypt!? Wtf? Where did that come from? So random, but an interesting development. Nodame will be meeting new people who will definitely start altering her mindset, most probably.
As for Chiaki, I agree with the sentiment that I pity him rather than sympathize with him. Now that Nodame isn't drooling over him anymore, maybe he'll understand what a great thing he has (or had...) with her. Still, regardless, I hope he ditches Brazil and goes after Nodame (granted he finds out where she went). Or that Nodame and Chiaki somehow randomly meet in Brazil.
