She had been raised to know when eyes followed her, when her actions were being scrutinized. It came part and parcel with her lineage; if you couldn't tell, you might as well open your neck up to the wolves.
So she knew, of course, that there were many eyes on her now -- at these parties, there always were. Lord Aristide Amell's promising daughter, newly engaged to the young Comte de Launcet; she didn't even have to strain to hear the murmurs.
But his eyes were not familiar.
She kept him in her sight from the moment she'd caught him looking - subtly, of course; it wouldn't do for a young lady to gawk - and wondered. She didn't know him, and she had been thoroughly taught every name and every face in Hightown and about half of those beyond; his name was a mystery and so was his standing - where was he from? If not Kirkwall, then where?
It occurred to her, after an hour of peeking from beneath darkened lashes and watching through her peripheral vision that she could, of course, simply ask. Nobody could fault her for speaking with him, surely.
That's how she finds herself face to face with this stranger, acting for all the world as if she hadn't noticed his eyes on her, as if she hadn't been watching him just as intently. She smiles.
"Are you enjoying the festivities, Serah?"
