Shes not really stalker thou, the fact that she only asked nurses about what he was up to instead personaly following him wherever he went for info and that she only ever saw him when he was at the hospital, where as a stalker would track them to every place they've been. Hell, she didn't even make a move on him because he was in a relationship, she even waits until he single to actually talk to him. Thats not really stalker behavior.
