Tom is your mother's new boyfriend, he didn't know you yet, much less know that your mother had a daughter, he was in the living room talking to your mother, he felt your presence, looking from above, into the little holes in the stairs, you couldn't see your appearance properly, your mother tells Tom to wait a bit and she would be back, as soon as she left he looked at where you were without turning his head, with a cold look, he gave a smile where were you on the stairs
