My thoughts as I read.  

OK, so Tenchi simply has no interest in Ryouko.  Poor girl.  

A unique approach to a trapped Ranma.  It's the only time I've seen her 
written with anything except lasting depression.  

Repair modules.   Plot device from the original, or is the author just 
filling in the blank? 

I don't much like the idea of Ranma switching gender orientations.  

Why is Ayeka calling Ranma "sama"?  Ranma doesn't outrank 
Ayeka.  "fiance", not "fiancee"

Really, Ranma should be working on some kind of counter to that cage 
manuever.  Letting a girl push her around that way has got to bug her.

Ryoko should probably call Ayeka "sourpuss" rather than "sourface".

Unless something actually interesting happens on the shopping trip, it 
is just as well skipped.  

It would be interesting if Ayeka's efforts actually managed to suppress 
Ranma's innate joie de vivre.  Of course in order for that to happen,
she'd actually have to convince Ranma that being un-ladylike was a bad 
thing.
