Yes, it was sad... I shed a tear.
That scene was really touching, and I agree with you, Nigredo's cool until the very end; also seconded your comment about Jr. uniting back with Albedo.

And chaos... o______________O;;; I thought that he was Messiah, but I don't think it would be like that... I hope. I just surprised when Wilhelm mentioned him...

My chaos is actually stronger than Jr. ^^;;;
