The Defender Showrunner Marco Ramirez, Charlie Cox (Daredevil), Mike Colter (Luke Cage) and Finn Jones (Iron Fist) explained how their characters intersect with each other across the series.
“None of us wanted to do the procedural version where they’ll go back into their own shows completely unchanged. The events of Defenders will affect each of them. It just really felt like in order to honor the individual character arcs of each of the shows, we needed them to realize this was the next big chapter of their lives, individually.”
He added concerning Matt Murdock’s ex-lover and the blind superhero, Per Cox:
“They don’t like each other. They’re too similar. They’re too stubborn. They’re too opinionated. They don’t have time for each other. The stuff that I liked filming the most were those scenes where they start to, against their will, like each other. They kind of respect each other. They would never tell the other person that. That was really fun to play with. That’s one of the things I really enjoyed about it. All of our shows had been quite serious, they’re tonally quite dark. But you can’t put someone like Matt Murdock, who wears a super hero costume in a room with Jessica Jones and not make jokes. You can’t.”
Finn Jones stated Danny’s guilty conscience concerning The Hand and losing an entire city:
“Danny is responsible for the loss of a whole city. He’s majorly f*cked up. The guilt that is heavy on his heart is really making him spearhead forward with this mission to take down The Hand. Danny’s very reckless in his behavior. He’s just punching things, throwing his cash around. He comes into someone like Luke Cage, who is the complete opposite, and Luke’s just like, ‘Whoa, kid. If we’re going to work together, you need to really realize a few things.’”
Mike Colter spoke concerning changes in Luke’s personality:
“The first four episodes serve to get him out of that world, and out of the mentality of looking over your shoulder, and worrying about your past. I think we will see a new Luke because of it.”
