The first day Bella spends out and about with her new who's-watching-me powers, she is rather alarmed.

Maybe she's just mistaken about how much time people spend looking at reasonably pretty eighteen-year-old girls. She kills a pentagon to try it on a nearby control - who's looking at that girl over there?

Fewer people. Fewer people are looking at that random girl, and less intently. They're looking at her familiarly - they know her - or casually - they're checking her out.

[I have a spy problem,] Bella says. She makes a faintly exaggerated show of snapping her fingers in frustration and turning around. She's going back to her room to get a mirror and bobby pins and barettes, so she can spy back on the pretense of checking her hair, without making it overwhelmingly obvious that she knows what's going on.
