Based on some research, it appears that the question may be related to the Star Wars universe and the character of the Third Sister. Therefore, I will provide an answer based on that assumption.
In the Star Wars universe, the Third Sister is a character who appears in the comic book series, “Darth Vader: Dark Lord of the Sith.” She is a former Jedi Padawan who, after the fall of the Jedi Order, became an Inquisitor, a group of force-sensitive agents who worked for the Empire to hunt down Jedi survivors.
Obi-Wan Kenobi is a key character in the Star Wars franchise and is known for his role as a Jedi Master who trained Anakin Skywalker (who later becomes Darth Vader). In the storyline of the comic book series mentioned above, it is unclear why the Third Sister is specifically obsessed with Kenobi. However, there are several possible reasons why she may be fixated on him.
Firstly, it is possible that the Third Sister is obsessed with Kenobi because he represents a powerful and influential figure in the Jedi Order. As a former Jedi Padawan, the Third Sister likely had a strong connection to the Jedi and their teachings. Therefore, someone like Kenobi, who is considered to be one of the greatest Jedi Masters of all time, may hold a special significance to her. Additionally, Kenobi was one of the few surviving Jedi after Order 66, the order that led to the destruction of the Jedi Order. As a result, he would have been a symbol of hope and inspiration for any Jedi survivors who may have been hiding from the Empire.
Another possible reason why the Third Sister is obsessed with Kenobi is because of his connection to Darth Vader. As mentioned earlier, Kenobi was responsible for training Anakin Skywalker, who later became Darth Vader. The Third Sister may have been fixated on Kenobi as a way of getting closer to Vader or even trying to turn him back to the light side of the Force. It is worth noting that in the comic book series mentioned earlier, Vader is shown to have a similar fixation on finding and killing Kenobi, which could have further fueled the Third Sister’s obsession.
Additionally, it is possible that the Third Sister is obsessed with Kenobi because of a personal connection between the two characters. In the Star Wars universe, it is common for characters to have complex relationships that are revealed over time. It is possible that the Third Sister and Kenobi had some kind of past relationship that has yet to be revealed in the comic book series. Alternatively, she may have simply admired him from afar or been inspired by his teachings as a Jedi.
Finally, it is worth noting that the Third Sister’s obsession with Kenobi may simply be a plot device used by the writers of the comic book series. In fiction, characters often have motivations that are designed to move the plot forward or create tension between characters. The Third Sister’s fixation on Kenobi may have been introduced to create conflict between her and Darth Vader or to add depth to her character.
In conclusion, while there is no definitive answer as to why the Third Sister is obsessed with Kenobi, there are several possible explanations. She may be drawn to him because of his significance as a powerful Jedi Master or as a symbol of hope for Jedi survivors. Additionally, his connection to Darth Vader may have played a role in her fixation, as may a personal connection between the two characters. Ultimately, the Third Sister’s obsession with Kenobi may simply be a plot device used by the writers of the comic book series to add depth to her character and create tension within the story.
