Answer: A script
Explanation:
A script is defined as the written texts of a play, filming, broadcasting or show.
A script contains a well described role an actor is meant to perform in a movie.
Emmie here seems to be an actor, because she isn't a real dentist. Emmie also knows all the roles she is meant to play when portraying as a dentist.
And she memories all the processes involved in this which includes going to the office, pretending to read a magazine, etc. Because it now seems like a normal routine for her.
All the routines she takes can also be scripted.
