Chapter 12 gives us Beneda's heart-wrenching cry after she witnesses Ryouga saving her life by taking the full force of Sailor Mars' Fire Soul. Her mind snaps in half, and the masquerade she'd been sustaining ever since she first met him follows suit a chapter later as a result, driving her into deep despair and requiring the grievously injured Ryouga to pull her out of it.
In Chapter 16, where it looks like we are being given a heroic Moon Kingdom origin for the Amazons involving a set of twins being sent Moses in the Bulrushes-like to earth in a lifepod, we wind up with this:
" Even today, back in China, in their most sacred shrine, lay the two small skeletons that had been found there as well."
The last three scenes of the third chapter of the interlude.
Genma's death at the hands of Tanizaki. He may have been responsible for much of the nonsense that permeates Ranma's life, but in the end he was still his father, and chose to do the right thing.
One of Tanizaki's guards is an ex-con who stayed loyal to his boss because he gave him a chance when others wouldn't, but when he tries to rescue a child that's meant to be a Human Sacrifice, he gets killed for it in front of said little girl.
The way Unit Zero keeps looking to Tanizaki for approval, like an abused child desperately trying to find out what she's done wrong to make him so angry with her, doing his bidding, hoping for just a smidgen of affection, is heartbreaking.
It's eventually revealed that it's not that Unit Zero doesn't want to speak, it's that she can't speak. As an Expendable Clone Tanizaki never put much focus on developing her mind, and the method Metzger used was thus needlessly blunt and caused permanent damage. Mercury suspects that she'll never mentally develop past a fifth or sixth grade level, though luckily, since the other clones were never decanted and had a chance to develop their own mentalities, the problem can be fixed for them.
In chapter 19 of Ascendant, we see the funeral for those lost, including Genma. Ranma not only has to plan the funeral and struggle with his feelings, but he also has to deal with the realization that his mother is truly still a stranger to him after all this time, and he has no idea how to comfort her.
Nodoka wailing and sobbing at Genma's grave when she's finally alone, after presenting herself as the ideal of quiet grief to everyone.
Ryoga and Hotaru's daughter is crushing on Ranma and Akane's son, but he's oblivious to it.
