Maybe she is being presumptuous, but it's on a solid foundation of experience. "I have known enough humans like you to recognize the type," she says derisively, "and to avoid them when I can." Not that the Doctor gives her much choice on that matter even when she makes her displeasure known. Nor did Gabriel. She tenses up with the remembered hurt of that fight and walks faster to reach their destination. Under an apple tree she comes to a halt and raises her horn up to the lowest hanging branch for Peter to finally get off for good, too morose now to even give him a dismissive order.
