These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Jon-Tom summoning M'nemaxa at the Battle of the Jo-Troom Gate.
Roseroar is pretty much a walking CMOA, but highlights include how she breaks Mudge and Jon-Tom out of Malderpot's jail and how she eliminates Corroboc.
Mudge's insult-fest that brings down the cage of insults.
Talea's rant against Braglob after she is freed from his compulsion.
I wouldn't leave now even if you agreed to it. I've been used. I feel used. I want to make that unseen bastard pay. He almost had me killed, which isn't so bad. But he tried to make you do it. That's dirty. I don't like dirt, Jon-Tom. I like clean. There's something up there that needs cleaning up.
Crowning Moment of Heartwarming: The entirety of Mudge and Weegee's relationship is this. The moment when Jon-Tom gets to listen to Couvier Coulb's collection of gneechee music, and learns that Beethoven, Jimi Hendrix, Jim Morrison, and Janice Joplin have all continued to create incredible music after death, is both this and quite the Tear Jerker.
Folly. Not only is she an orphan who has lived her whole life in slavery to Corroboc and his pirates, but she just continually gets put through hardship after hardship—getting mugged, getting taken to the Friends of the Street, getting kidnapped and ensorcelled by Jalwar/Zancresta, and finally sent to kill herself in a lava tube. Her persistence in pursuing Jon-Tom aside, one can hope she was finally able to make a good life for herself after they returned with her to the Bellwoods (or wherever she went).
