That's true. But how she will do it? Geralt appeared near Kaer Morhen without memories. No info about Yen. Maybe Lodge was looking for her, and near the end of TW2 - they got info about her (Sheala knew that she is in Nilfgaard).
I don't think the Lodge was looking for her. They probably learned her whereabouts from Assire and Fringilla.
