Amelie wanted to make the conflict between Cynthia and Prosperity Global Entertainment worse.
She knew that all the buckets assigned by Cynthia were all of the same size, and they could be found in the water room not far from the practice room, but Amelie deliberately asked Janice to find a large bucket to collect more water, so that she could pass across the conference room of Lamont, which could attract Lamont's attention.
When Lamont knew Cynthia's plan, he definitely would rush over for he would have thought that Amelie was afraid of heights. In other words, Amelie was just betting her life.
"Have you thought about what would happen if I didn't come, or if there was a slight error in time?"
There was something wrong with that high ladder in the first place, anyone who went up would fall down, Cynthia had no idea that Amelie was afraid of heights, otherwise she wouldn't have made such a risky move.
