She might try to find a way to reverse it while also dealing with the physical and emotional changes. For example, her fighting style might change due to her new body structure. And other characters like Blake might react in various ways, from shock to sympathy, which could further develop the story.
The character development would be quite complex. Adam, now a girl, would first have to come to terms with the physical changes. This might involve dealing with different body mechanics in combat and everyday activities. Emotionally, she would have to re - evaluate her relationships.

She could also develop new traits like more empathy, which might come with the change in perspective that often accompanies a gender change in this type of story.
