当阿布斯泰戈定位了刺客领导人威廉·迈尔斯时，韦迪克和英格兰将这些圣殿骑士大师召集到她的办公室里，并下令组建了一支“弥补小队”。 She later chastised Berg for hesitating to move against William, who was posing as a guide leading a number of schoolchildren, ostensibly to prevent the children from being harmed, showing that she had no qualms about innocent casualties; she also subtly made a threat towards Berg's daughter, who was showing a remarkable recovery, which Berg was not happy about
In 2013, Laetitia supported Abstergo Entertainment's efforts to use the Animus to locate the Observatory. Though she desired immediate results, Olivier Garneau and Melanie Lemay said it would take time, but promised that their best employee would deliver. However, Olivier went missing en route to the shareholders meeting and Laetitia had no luck finding him.
Laetitia unknowingly investigated an image of Juno found in an Abstergo Entertainment product. She talked with an unknown person over the phone about how her investigation was going, implying she had even made contact with Erudito to figure out what the image was.
Sometime after the Precursor box was recovered by the Templars, Laetitia called Berg to her office. She ordered him to deliver the box to Álvaro Gramática in a top-secret facility, of which even she did not know the location. Before Berg could leave, she reminded him of the urgency of secrecy.
- Laetitia is a Latin name meaning "happiness, joy".
- Laetitia was one of four members of the Inner Sanctum who were a part of the Operations division of Abstergo, the other three being Daniel Cross, Isabelle Ardant and Otto Schmidt. In total, the four made up half of the Templar Order's Inner Sanctum until Berg's induction.
- In the non-canonical modern day storyline of the Assassin's Creed French comic series, Laetitia is the head of two Abstergo Industries initiatives: Project Hydra and Project Horus.
