Hmmm, if they had just asked her to donate blood regularly nicely, I don't think she would have refused. Instead, they decided to go that way when things happening to her will only backfire. She doesn't need any protection, sure, but just asking her to donate some blood and to do a few favours while working so no one else can get her would definitely be a deal which would profit them immensely. Greed is going to backfire hard.
