Elle recalled back when she was still living with Grandpa John, the old man warn her of the most dangerous trick when it comes to stealing, that being the trick of "attracting a prey by beauty".
It is inherent in a human's nature to feel attracted to something or someone who is considered to be on the prime of beauty. Magnus's face was the excellent example of that "Prime beauty".
