On Evie's first day in his class, Mr. Deley attempts to humiliate her by asking her about the atomic weight of silver. Evie, however, manages to cheat by using her Magic Mirror that she hid in her hand
When it came time for a test, Chad stole her mirror and gives it to Mr. Deley, who later uses it as an excuse to recommend Evie for expulsion. Doug begs him to give Evie a chance and Mr. Deley agrees to return Evie's mirror and let the matter slip if she passes the test, which she does with a B+.
