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.
Fanon: It's never made clear in canon whether Iris's surname is Fey or Hawthorne. The author takes the former as Canon.
Although it is justified in the story proper. Without the DL-6 incident happening, Morgan's first husband never divorced her. Since every woman raised in Kurain Village had the surname Fey, Phoenix decides it stands to reason that Iris was raised under that name as well.
Jerkass Woobie: Alternate!Pheonix, from what we heard of him, was actually an okay guy until some undefined "incident". If it's enough to excuse his actions or at least leave something to be redeemed is yet unknown.
Tear Jerker: The way Maya treats Phoenix. As justified as it is from her perspective you can't help but feel for our hero. And let's not forget Ema's death.
The Woobie: Canon!Phoenix. Stuck in a world where everyone he knows hates him and stuck prosecuting an innocent woman.
Canon!Phoenix becomes a different sort, but still a massive Woobie when it turns out Alternate!Phoenix was once somewhat loved by those around him, but now Canon!Phoenix has to deal with not being able to fill his counterpart's void. Most evident when he interacts with Iris.
