The Japan thing unfortunately makes some sense.
But here's the thing, when was the last time Kallen even mentioned Japan? In addition a chat between Suzaku and Kallen about Japan should have happened while she was captured or before she tore him up during episode 18? It makes more sense then not now.
It wouldn't make much sense for them to bring Japan up now when Kallen and Suzaku's fight should be based on two things.
1) Getting to/protecting Lelouch
2) Settling and old score/warrior's ego.
Japan doesn't really fit in IMO
