Take the following as truth: I've been flying when I could for three days now."  Bork, of course, hadn't known of her spell with which she'd forced herself to want him "well and truly." Apparently it had gone on operating even when she thought he was dead, and with a built-in sense of his direction.
Then the following statement: "She had made sure not to cast any spell on Bork." is true, false, or inconclusive?
Answer: False
