Yeah, there's Jessica Jones, formerly Jewel, formerly Knightress, now just a private detective, and there's Jessica Drew, the Spider-Woman. Same first name, vastly different characters. They teamed up in the comics to rescue yet another Spider-Girl, Mattie Franklin. Don't know if that's how the show is going to go. I sincerely disliked the whole Jessica Jones story (way more morbid than I'm used to, at least when it concerns female superheroes) so I wish they would have just done a Heroes for Hire show that would focus on Iron Fist and Luke Cage/Power Man and had the others, like Daredevil, just be cameos or recurring (like Punisher, too).
