Although Amy was still childlike in temperament, having been trained by two high-ranking god-kings, her intelligence far surpassed that of ordinary people.
She could certainly guess that William was very strong, both from the way her masters treated him and from William's own actions along the way.
In any case, Mr. Johnson was powerful, but to what extent, she didn't know.
Children shouldn't speak recklessly, so since Wes asked her to go out and rescue people, she followed him.
Wes wasn't the absolute authority in Arcane Village,he didn't have the power to order the entire city's army to charge out of the city and into the beast tide.
Especially not just to save two people.
If trying to rescue William and Hugo resulted in even more casualties, it would be a loss too great.
Amy was ranked eleventh among the strongest humans. With the two of them in action, things might be better, and they would be more agile.
