I don't think we're meant to feel sad for Ruby, but to gain insight into how she became an arrogant troll sum literal monster. Well done. For a talk no jutsu chapter, there was a lot of nice parallels between past and present. The youthful fistbump promise turned into fisticuffs! Child Ruby complaining and saying there was no point in trying hard, while making a snowman of the monster she'd eventually become. Her hard work fueled by resentment, while Lloyd's was filled with gratefulness.
Best chapter of the series, imo.
