"It had been two weeks since a dynamax anomaly caused Gloria to grow huge. She had enjoyed her time as a giant, but what came next almost made her regret it. For a week after the incident, everyone looked at her like a ticking time bomb. Shew wasn't allowed into any building for fear she might spontaneously grow and demolish it." - The People in Galar don't have grasped the concept of an "Anomaly" yet, have they?

"She searched the stands for Victor  and saw him cheering for her from one of the front-row seats." Very minor, but there is a _ too much between "Victor" and "and".

"As she pondered this, she sensed a resonance between herself and Nessa, and then she found herself growing to match her size, her sudden growth catching both of them off-guard." - Wait, so the people treating Gloria like a "ticking time bomb" were NOT wrong?

"The tiny things didn't seem to be the least bit fazed by their size, happily letting her scoop them up and nuzzle them against her cheek." - Given the Dynamax nests have been there since the "Eternal Night" minimum, the Pokémon had a way longer time to adjust to gigantic beings, gave the people a few generations and they won't erupt in panic whenever someone grows. (Btw will there be male growth or are the anamolies drawn to female bodies by some "mysterious force"? :P )

Interesting that you gave Gloria a "Rehabilitation Arc" at all and so quickly, too. (I didn't think she did something wrong at all and "rampaging in Motostoke is definitely an exaggeration, that's borderline "malicious defamation").

I'm surprised that you've continued Gloria's story at all, really. I expected the story to be comprised out of loosely connected vigniettes about specific characters. There is nothing wrong with your choice, it's just unexpected.
