Not sure exactly where you are, as there are several spy on Rachel steps. I did once get a long delay when another class event took precedence (pretty sure it is the one where Cassandra mouths off and you don't get a punishment type option, you immediately tell her to come to the office, as I have had that block three different advance arcs), and so I did not get the scene where Emily tells her about the adult DLC add-on for her game. It took a while for it to come back, and not sure if that was random, or just that I finally repeated a trigger step that I didn't know I needed.
