First of all it
seems that this series will at least continue for at least another
season. Then to this end the question become why did Nobunaga request
to drink tea with Caesar. It appears that part of his goal was to
seek to understand Caesar because he took him to lightly and because
of his short sightedness has resulted in the situation that they are
in. That is why his main goal is the use the tea ceremony to gauge
Caesar character and see the true nature of his agenda. Also he is
doubtful that he didn't shoot him in the back just because Jeanne was
with him. That if his true goal is the Shinki and their users then he
wouldn't seek their death only their subjugation.
Although most of
this episode has to deal with the underlining issue of this tea
ceremony but largly it about give Ichihime a time to shine because up
to this point she hasn't been a major part in the story. That with
her being the host of the tea ceremony she end up taking a leading
role in the conclusion between Caesar and Nobunaga. Then at first it
look like they would be unable to come to an agreeable terms because
Caesar wants the Shinki and this is the on thing that Nobunaga would
be unwilling to conceded to. Then Caesar uses this this failure to
obtain what he desire from the first time he layed eye on her,
Ichihime. That he uses this alliance to acquire her hand in marriage,
and Ichihime accepts his proposal if it can help the Oda. However she
is determine to kill him if he betrays his word to both her and her
brother. That as this alliance is made a crack is formed in the
western star, the question is what does to omen foretell.
