She remained loyal to him throughout the duration of the Tragedy, obeying him without question when he ordered her and the others to kill everyone in the mansion, even though she didn't understand why he would ask them to do such a terrible thing. Her faith in him never wavered, even when Jack was declared a hero she still believed her Master had been betrayed and she fought hard to find the Sealing Stones and to discover the truth behind the Tragedy so she could bring him back from the dead. Everything she did after being released from the Abyss was out of service to her beloved master, although it is uncertain whether she still harbours strong feelings for him like before. It is likely her love for him has diminished now that Leo has become the vessel for his soul and Oswald can no longer take his own human form.
Lily is another member of the Baskervilles. She and Lottie often work together as a team. They have a close relationship, and Lottie seems to enjoy doting on her like a little sister.
The first time they met was the day Lily showed up at the Baskerville mansion, having been led there by the golden lights of Abyss to become a servant of the next Glen. Lottie quickly took her under her wing, fussing over her appearance and fixing her hair for her in much the same way an overbearing older sister would, making her a part of their little "family".
When Lily was released from Abyss, Lottie was the first to greet her, comforting the girl while she cried and assuring her that they would find Master Glen. They are often seen together at meetings and during missions, and are closer to each other than any of the other current members of the Baskervilles.
They meet yet again at the Second Coming of Age Ceremony where Break finds her and after she disarms Isla Yura. She tells him that she knew he was close by, prompting Break to tease her and ask her if she could sense his presence. Remaining serious, Lottie says no, but also tells him: 'Somehow, I knew you'd make an appearance." She asks him what he meant when they were in Sablier together. Break says that she's a reasonable woman, and, with a smile, he asks her to join forces with him. Lottie is shocked again by his words, and Break quickly says that there are a lot of things he would have told her if he had the time.
After this, Break calmly demands to know where Reim is, warning Lottie that if he is dead, he will abandon all forms of a 'friendly solution' with her.
When Isla Yura orders his servants to attack, Break and Lottie presumably fight together to kill their attackers, as when they reappear, the cloaked figures lie dead before them. Lottie confesses her anger to Break, wondering if someone is trying to make a fool of the Baskervilles.
When Dug and Fang drag her away, Lottie warns them not to fight against the Hatter, as they cannot defeat him.
As of the latest chapter, it is hinted that Lottie is guarding Break as well as Oz after they are imprisoned by the Baskervilles.
