Possibly she shows up at some point in the movie and she is probably pissed off beyond all reason. Other than that, I don't think that there is anyway for him to find out unless he accidentally watches a news report about the break in at the hospital, and reporters mention a patient who survived a fall from the top of the building. But whatever happened to Laurie's son? (The one played by Josh Hartnett, the characters name fails me at the moment) Why wasn't there any mention of him in Resurrection? Did he know that she was put in the hospital in the first place? Was he the one who took her there? So many questions, so little time.
