Dom said he didn't like girls that swore, which contented me, as Jamie was a serial swearer, chanting her effs and sugars like a menopausal dinner lady. Jamie had an unnatural affection for Dom, though I could detect no chemistry and knew that she saw him as "a good lad" and nothing more. So when he spent evenings at her house, looking after baby TJ and watching soap operas, I believed him when he told me that there was no sexual contact.
Sex can only occur between two of the same species, and although Jamie was very much and definitely human, Dom was purely angelic - he just had invisible wings.
