I believe we just got done with the Vmc demo and shortly after she asked me to do an emergency descent. At this point I knew all that was left was the descent, and then SE instrument approach. I’m not even sure there was a “scenario” for the descent such as engine fire or something. She just said emergency descent. So in fairness, she didn’t really stack any failures.
Thanks everyone for the replies and reassurances, I really do feel better about the whole situation!
