Trimmle 应命立刻消失了，好像很庆幸自己离开了房间，当她再次出现时，带着焦躁的下属，玛丽已经恢复了镇静，并让她的问题得到了解决。

Instead of being the teacher's pet, who liked  to read, he was now a hardened, toughened boy who was willing to please his urges at the behest  of others and with no regard for the consequences.

他不再是喜欢读书的老师的宠儿， 而是一个铁石心肠的男孩，愿意听从别人的要求， 不顾后果地满足自己的冲动。
