If Nobunaga had heard of
Julius Ceasar, he would probably have thought twice about refusing to repeal a banishment. Or rather, even if he did know where Ceasar's ambition ended up, he would keep on following his star in any case, which is the point of the play.
In the same context, Sasuke reminds me more of Falstaff, someone completely upfront about his numerous flaws who seeks advancement unashamedly (though Falstaff drinking tea is a rather unlikely image).
I really like the subtle dialogue in this series; it seem very much about personalities rather than history. Actually I also like the effort being put into different costumes; fitting enough when the characters are having to adopt different faces in various situations (Pink with spots was a bit of a fashion crime in ep 4 though).
