| — Penelope to Chloe|
Penelope seems to have always been at disagreement with her daughter, Chloe. They had different opinions regarding Chloe's profession. Penelope is the one that pushed Chloe towards acting, which, at first, seemed to be the right choice. Chloe enjoyed the profession, but after a certain embarrassing movie, she quit. Her relations with her mother started to worsen. Before leaving to continue her career, Penelope asked Chloe to move to her house in L.A. Chloe accepted her offer.
After her return to L.A., Penelope wanted to see her daughter. In order to be able to do so, she had to say that she's Chloe's sister in order to be allowed to see her, because she knew that Chloe wouldn't want to see her.
Chloe was not enjoyed by her return, but Lucifer was amazed to finally meet her. She wanted to bring Trixie into acting too, but Trixie herself prevented that by running away while her and Chloe were fighting over Trixie's future profession. Before leaving, she finally set things right with her daughter, apologizing for not being the mother Chloe wanted. Despite that, she claimed that she had always wanted what was best for Chloe.
Lucifer has called her the "Queen of '80s Cheeseball Sci-Fi", being a huge fan of hers.
In "Once Upon a Time", which takes place in an alternate universe created by God, Penelope is married to a still living John Decker. John tells Chloe that Penelope told him to tell her to tell the people working on Weaponiser 5 to get Chloe's good side, suggesting that Penelope is interested in Chloe's career.
Her personality seems childish, playful. She is easily enjoyed and tries to enjoy the people around her, too. However, she can be serious when discussing important subject (mostly when fighting Chloe). Even though she seems to be at a continuous disagreement with her daughter, she cares for Chloe and has always tried to make her happy and to do what seemed best for her at that certain point.
