This makes me feel all warm and fuzzy inside.
Because Suzaku's pretty much had shit-all for family since he was eight, hasn't he? At least Lelouch has had Nunally with him all this time. I bet Kaguya had to go into hiding once Japan fell, so he's been all alone for more than a decade.
I wonder if he does see Lloyd and Cecile as part of his family. Cecile certainly treats him like a kind of son.
