You know, I have a small problem with this...

Okay, Akane's had sex with Ranma.  Ranma was a cat at the time.  Therefore,
Ranma doesn't remember having sex with Akane.

So far, Akane hasn't talked to Ranma about it, and hasn't even THOUGHT
about talking to Ranma about it.  Nabiki and Johnathan (that's an unusual
spelling of the name for me- my (half-by-birth, full-by-adoption) brother's
name is Jonathan Ken(ji- removed when adopted) Tatum) haven't either.
Ranma should also be wondering what's going on, because Akane's definitely
walking differently and Ranma, being a martial artist (esp. one of his
caliber), would definitely wonder about it- even if Akane was consciously
trying to hide it (you need to be able to see where your opponent is
injured so as to exploit it).

You're right, I need to explain what's happening better.  Akane is hiding her
pain, she's almost as good as Ranma, and can pull it off. Not to mention she
just finished a fight with Shampoo and Happosai, which is a good excuse for a
little limp.  She doesn't want anyone to find out about having sex with Ranma,
because Cologne would curse Shampoo with the Cat's Tongue, as well as leave
Kasumi the way she is.  Kasumi and Johnathon know what happened, (Or at least
suspect, in Johnathon's case.) But they also know what Cologne would do, so
they can't talk about it.  Kasumi would have talked to Akane about it more, but
she was turned into a cat before she could.  Johnathon doesn't know what to say
to her, he feels guilty that she had to protect him.  But he's dealing with his
wife being stuck as a cat, and his guilt isn't helping him cope.

In fact, it's almost like the whole incident never happened...

Everyone who knows is trying to hide the fact it happened to protect Kasumi and
Shampoo.  They can't talk about it easily.

I'd do more complete reviews, but I'm a little short on time, and have lost
of other stuff to edit by obligation (a couple things for people who can't
use the FFML, and then I also preread for Lord Archive who sends out stuff
rapid-fire... and so on) but I think your series, while quite interesting,
needs some work for a number of things like the above.  The plot seems more
disjointed since they got back from China, so maybe you should slow down
for a while and check back over what you've written...

Good points.  I do need to do some editing.
