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.
All Just a Dream: The ENTIRE FUTURE ARC, which received a huge amount of backlash from fans for being an Ass PullShocking Swerve of the entire theme of the series, turns out to be just a dream Cassandra had (which, ironically, is considered even MORE of an Ass Pull by the fandom to try and Retcon their way out of a poorly thought out arc.)
Complete Monster: Doctor Chu is a brilliant scientist who gets most of his results through torturous experiments on live subjects. Or, put another way, he's a professional torturer who learns a lot of useful things while on the job. Either way, he certainly enjoys what he does.
Les Yay: Metre, Andora, and Cassandra appear to have a three-way... thing going on.
Stop Helping Me!: Subverted. When Enki "aids" H'Mbawa fighting Hurk and his group he is more of a hassle than a help, but turns out his intention was avoiding harm to the Ulympean crew.
