This moment was real and it was the last straw for Sarah Lynn. This was the moment where Sarah Lynn gave up. In this scene, you can see in the background that Sarah Lynn had written notes like “I love me” and “don’t forget yourself” or something like that and she had written them because while her life was hard and causing her to suffer she still was strong and had hope for herself. She wanted to keep her light alive. Then, Bojack came in and she is so happy because she feels like the person that she has looked up to so much, has hope for her too, and is proud of her, and supports her. But, when she realizes that he was only there to use her fame in order to get more attention on his show, she looses all strength. Her light dies. She gives up. This was when Sarah Lynn died because she now knew that there was nobody there for her.
Mindy Kaling for PC? I mean I think physically she would suit it because she has cat like features and i think her personality would work, although apparently Mindy isn’t the best person to be around (so I’ve heard she could be lovely)
