In the episode, She-Hulk manages to track down an android named K.E.V.I.N., based on Marvel Studios president Kevin Feige, and she has some complaints. While Coiro was worried about upsetting the fans by making fun of the MCU, she said that Feige was completely game:
“Kevin had a huge hand in that finale and in the character of K.E.V.I.N. Ironically, I was more squeamish about it than they were. I was like, ‘Are we going too far? Are we throwing Marvel and fans under the bus by putting down Marvel films?’ They have such a self-deprecating, irreverent sense about themselves and were totally willing to poke fun at themselves. Any criticism you can lob at them, they have thought of.”
You have to grow a pretty thick skin to be a creative in the public sphere at all, and I imagine that you have to have a skin of adamantium to survive being in charge of something like the MCU, so it makes sense that Feige and the rest of the team have a good sense of self-deprecation. When it comes to worries about other characters popping through the fourth wall and doing the same thing, Coiro said not to worry, because “the glitch has been fixed.” Allowing every character in the MCU to break the fourth wall would dilute its meaning and honestly get a bit annoying. Let’s leave that to She-Hulk and Deadpool, who have been doing it in their comics for years.
