In the Alias comic book series, Carol Danvers was the best friend of Jessica Jones. However, with that character now set to receive her own movie as part of Phase 3, it wasn't feasible for her to show up in Netflix's Jessica Jones, but what role would she have played had that been the case? As it turns out, pretty much exactly the same as her comic book counterpart! "Back when it was at ABC Network, I did use Carol Danvers," Melissa Rosenberg explains. "But between then and when it ended up on Netflix, you know, the MCU shifted, and it also shifted away from the universe in the [comic] book. So in the book, the powers are very out in the open and the themes of that are about ‘the other,’ and in the cinematic universe that’s not the mythology. So there was a lot that I had to move away from, just in terms of sheer plot, and Carol Danvers got her own movie."
However, the departure of Captain Marvel from the series meant that Trish Walker (better known as Patsy Walker/Hellcat in the comic books) could step up and take over the role of best friend, albeit in a ver different way. "But as it turned out, Patsy Walker ended up being an incredibly—a much more appropriate fit with Jessica. It was better that her best friend was not someone with powers. It actually ends up being a really great mirror for her." It would have been pretty cool to see a fully costumed Ms. Marvel - as she was known when A.K.A. Jessica Jones was being developed - in the series, but Trish is great, so it's not the end of the world. What do you guys thinks?
