When Abaddon reset the timeline, Lillian, unlike the rest of her sisters, got to live a life that was exceptionally better than her last one.
She maintained her life as the nanny for Exedra, Malenia, and Kanami, but this time she never met an unfortunate and heartbreaking end.
Exedra had eaten and absorbed the soul of Jeddah in their first encounter in the prime timeline.
Even before he had become it, he had already sent a soul toiling around in oblivion. Meaning reality re-wrote itself as if that particular chess piece was never on the board.
Lillian got to live a busy, but otherwise happy life as a worker in the castle.
Although she was a bit bothered by the fact that she was single that entire time... She would later find out that her future husband was paying his baby sister to light the butts of anyone who approached her on fire.
Years later, he insisted that they were the best butterscotches he'd ever spent.
