This reminded me of how much I generally dislike lazy foreshadowing. Things like "[...], but she didn't know that yet", "she will learn [...]", "soon, she will see [...]". It works well as a teaser, but it's so easy to do that it gets messy easily. It also trades its advantage in hype value for a loss of surprise. When you do this more than a few times, you end up unable to surprise the reader as they already expect every twist to happen.
