since they're so embarrassed about went on there; Ryoga
wouldn't either, since he isn't the type to blabber about
that stuff (or Mousse). Certainly not Shampoo, since she still
wants Ranma, and would no way let anyone know what happend.
That only leaves Genma, who I'm not too sure was at the
scene, and even if he was, he may have not noticed it,
being under Shampoo's command and all.

Genma noticed.. in my way of thinking... that is why he forced
Ranma and Akane to get dressed and set up for the wedding when
they got back... I am just inserting the probable scene when Genma
returns, sobs with Soun about how romantic Ranma and Akane were (with
Nabiki within hearing range), and then bonk Ranma over the head
and put him in a suit... :)

In the manga, Akane chose of her own free will to get married to Ranma
because she knew she loved him, and she knew he loved her, due to what
Ranma had been saying to her when she was 'dead'. But her father told
her that he would give Ranma and her the nanniichuan water at the
reception, so that Ranma could be a full man again. Akane only told
Ranma about the water after they were fighting, and she said something
like 'if you don't marry me, you will regret it'. That's why Ranma
suddenly runs off, talking about the nanniichuan water. Akane could
have told Ranma about the water to begin with, but she WANTED to marry
Ranma, so she didn't tell him... This is why I'm happy (not completely
happy, just happy, since they didn't kiss... bleh, they should have
kissed) with the ending. Ranma and Akane both know that they are in
love (however embarassed Ranma is about it), so they will get married
in the end. ^_^

Kun-chan...
