Jeremy Thompson opened the door with puzzlement, and when he saw Jeanette Warren standing outside, he was completely taken aback; he really didn't expect this woman to come looking for Anna.
Actually, he was not familiar with Jeanette Warren, and could almost say he had no impression of her at all. If his father hadn't told him that Anna was Xander Ainsworth's daughter, he wouldn't have investigated, nor would he have known of Jeanette Warren's existence.
Anna indeed resembled Jeanette Warren a bit, but she clearly possessed a more intrinsic quality than Jeanette Warren, though he wasn't sure if this was because Jeanette Warren had spent too much time in the entertainment circle.
Similarly, Jeanette Warren hadn't expected Jeremy Thompson to be the one answering the door. She thought that since today was New Year's Day, the pregnant Anna would surely be at home. She had come to mend the relationship with the siblings.
