As for Kodachi, she is not crazy despite what everyone seems to belive.
People have always associated her laugh with maniacal mad-scientist
cackling, and so went a step further and associated her with a crazy
women. Lawson's portrayal just fortified this bizarre interpretation,
and over the years, the Kodachi as mad women has become canon. Her true
character is that of a wicked women, a parody of a machiavellian court
maiden; she's as sane as she is underhanded, which is to say, very.

Try reading the source material before making such a claim.

In one manga story, she paralyzes Kuno, binds him, then feeds him to her pet
alligator.  Nothing very machiavellian in that; she wanted Kuno out of the
way and thought that would be the best way to do it.

Now, of course RT was just doing it for a laugh (we later see that Kuno
managed to escape, although we are never told how he did).  But it *is*
consistent with a Kodachi who is not altogether there.  And this is just one
of many examples I could quote.

What I'm saying is that portraying Kodachi to be mentally unbalanced is
*not* bizarre.  It is consistent with the source material.  Some may decide
to characterize her as completely sane; that's okay, too.  There's room for
interpretation here, same as in *all* of Takahashi's characterizations.
