As soon as the car passed through the school gates, Alicia sighed out in relief. Ezekiel did not stop the car or gave any reaction at all. So she thought that Ezekiel most probably did not notice Lilith who was there at all.
And even if he did catch a glimpse of her, Alicia told herself that there was still no way Ezekiel could have recognized Lilith in that crowd and in just a single short second, because Lilith was in her perfect human disguise. Alicia could recognize Lilith in an instant despite her disguise because she was in her spirit form and this form allows her to see through the outer disguise that was put on by any spells. But it would be very hard for any other creature even for their fellow witches to be able to recognise Lilith to be a witch.
