In the original Asimov books, it is unknown if Dors has been repaired after the damage. Seldon's last words, in the epilogue of Forward the Foundation, were "Dors!", yet it is not specified, if he met her, or if it is only an exclamation of a man longing for his dead spouse.
Dors reappears only in The Second Foundation Trilogy, after her apparent death, having been repaired by Daneel. She is originally assigned new duties, but has difficulty adapting to them. Having been built for the specific purpose of caring for Hari Seldon, her absence from his life and her knowledge of his impending death give her new perspective on Daneel's orders. Eventually, she leaves his service entirely, and it is implied that she takes up with the robot Lodovik Trema, but only after one final visit to her husband, whose last recorded word was her name.
