If nothing else, this promises that Daredevil hasn’t lost sight of the qualities that make the behemoth crimelord so interesting; all evidence from the fallout of The Defenders suggests an adaptation of the Born Again storyline, which means Fisk and Matt Murdoch are about to get very personal in their war.
Fisk is still a man driven by trauma and emotional baggage, which means the next season of the show is going to continue that trend.
Wilson Fisk has become a considerably more ruthless and cold member of the criminal underworld since his big reveal at the end of Season 1 (and his fight with The Punisher in Season 2), but that doesn’t change the emotional nature of his story.
