Please see the beginning of the episode Mr. Monk Stays in Bed for reference to the levels.

A confrontation was in order. Really there was. After continuously distilling the importance of even numbers into her mind, he does this! To anyone else, this would not seem like a big deal, and most definitely not something to get worked-up over. She, however, was not anyone else. Which takes her back to the reason a confrontation was needed.
Mr. Monk had asked her to take his levels to get their annual re-leveling, but that's not the point! The point was that he had three levels. Three! An uneven number if she ever saw one. It was apparent that she needed to remind him that three was not an appropriate number to have for anything.
Maybe she should buy him another one so he would have an even four, or, better yet, buy him seven so he would have an even ten. Yes, she thought, that would be the best course of action. It would, hopefully, get her point across as well.
Setting her plan into action, Natalie began to mentally prepare herself. She had a numerical fact to set straight with her boss.
