I feel like in the first episode this season they foreshadowed pretty well about...

Spoiler!

Mary being a spy or agent of some sort. Off the top of my head what stood out to me was the "skip code" thing. I told my girlfriend she has to either be somebody like Sherlock, which became clear she isn't or she is some kind of intelligence agent. At some point I think I remember her making a comment to herself out loud about Sherlock being who he is or something like that. Can you help me think of some other hints?
