Why is this a problem? Well, Ranma gave his word that he wouldn't
tell Akane about Ryouga's curse. He even goes out of his way to *PREVENT*
Akane from learning of the curse, going so far as to put himself into the
path of the hot/cold water which is going to dump on Ryouga in the Kodachi
story. Admittadly, the word was originally given to the dog, but he
obviously is keeping to the spirit of the promise, as he didn't tell Akane
about the curse when he found out that P-chan was really Ryouga.
Just a comment. I believe that Ranma is intentionally sparing Akane
the potential heartbreak and feelings of betrayal and disgust should she
find out that P-chan is Ryoga. That and the promise, which Ryoga uses to
unfair advantage.
Basically, Ranma will *NOT* do such a thing, and please, fanfic
authors, if Ranma *MUST* tell Akane, give us a reason. That reason cannot
be to spite Ryouga, for he'd have told before if that were the case.
Even should Ryoga do something HORRIBLE to Ranma (all ye lemon fic
writers out there, take heed), he still wouldn't say a word to Akane, again
because I think he wants to spare her the pain. No sense dragging Akane
into his vendetta.
