4) Jeri Hogarth
So far, Jeri Hogarth has been something of a crossover character; like Claire Temple, the lawyer has appeared in both Daredevil and Jessica Jones. The odds are, then, that she will likewise turn up in Iron Fist.
Despite her role in those shows, Hogarth traditionally has a larger connection to Danny Rand. In the comics, Jeryn Hogarth (for the character was changed to female for TV) was a friend of Wendell Rand, Danny’s father. He later became the lawyer of Iron Fist’s superhero organization Heroes for Hire.
Given this, it seems likely that Carrie Ann Moss will have a significant role in Iron Fist. And while it doesn’t seem as likely to happen, it would also be awesome if she got to harken back to her role as Trinity in The Matrix and join Danny in doing some martial arts.
Furthermore,, now that Matt’s old pal Foggy Nelson is in Hogarth’s employ, can we expect him to appear in Iron Fist as well?
