Jen's confused and upset that her show, which she always wanted to be a legal comedy, was about to end in a big super-powered clash between three Hulks, Abomination, and Titania, even though it made absolutely no sense. Rather than have the same finale as every other MCU project, she punches through the Disney+ menu screen and enters Marvel Studios itself, where she instead confronts Kevin Feige (represented by a GLaDOS-style robot) and negotiates with him for a different, more grounded ending that does away with the "stealing She-Hulk's blood" plotline.
