I really do have to compliment how
MorriganRae shows/writes Trauma. Now I'm no connoisseur of the subject, but I do recognize it when I see it. And while there are many ways to show it off, not all do it in a panicked or visually psychological way; in those cases, I believe THAT is when trauma is show at its finest, aka seeing how much it effects the person in real time. The rest are either slow burns with no out bursted pay off, or exposition that suddenly explains why the outburst happened without having any prior knowledge.
Best examples I can think of off the top of my head are Jinx Ep 3 & 9 from Arcane or Eren S2 Ep 12 from AoT. But while those 2 are like literal psychological breaks, Ashe's in this game is more..."consuming" in her own head. We don't really SEE her have a break in the real other than after the events of helping her sister move in, but when she attacks herself in her own head with foreshadowing to more, I feel that's where the writing really shined, or at least, resonated with me. It's those inner thoughts of hopelessness eating away at her psyche that make it stand out just as much as the other examples I mentioned, but in a less physically reactive way.
The music also helps, even when we only see the woman and not Ashe's alter ego. It shows she's in control of herself, but as the conversation takes a turn towards doubt or curiosity, the music begins to play, signalling the inevitable bottled up darkness waiting to be unleashed in her mind. Jinx's breakdown is less musically supported and more visually drawn, along with the camera work and physical body movement. While Eren's breakdown is almost musically deaf with almost no camera work, to allow the viewer to focus in on his verbal cries of sorrow and hysteria to show how everything effected him. So Ashe's hope and sudden loss of control, all while everything is symbolized in her head as the scene or music progresses makes it unique in the way the trauma/breakdown is portrayed.
I do hope we see more of those moments, don't lose that skill, it's very hard to capture a dark or at the very least sad scene that captures the CHARACTER's reaction rather than trying to focus on the scenario as a whole.
