What is the significance of the third note which Miranda finds in her coat pocket?

Finally, Miranda finds a third note in the pocket of her winter coat. This note has three things on it that appear to be events that will take place in the future to prove the authenticity of the writer. This again suggests time travel or foreknowledge of events about to take place. This touches on Miranda's favorite book, a book of time travel, and a conversation Miranda had with Marcus once.
