The main spoilers are down for Daredevil Season 3, so it would not be wise to continue reading without having seen all 13 episodes.
In many ways, an adequate bookend for its 2015 debut season, Reckless Season 3 brought his post-The defenders Matt Murdock returns to the land of the living. While none of the other MCU heroes appeared to help in the search for Daredevil to eradicate Wilson Fisk once and for all, Season 3 introduced several new faces of varying importance. In addition, he added new narrative layers to all the well-established characters that the fans have invested.
When the dust at the end of season 3 settled, over several pools of blood, sweat and tears, Hell's Kitchen was a different place, as were its many citizens. While we wait to see if Season 4 is going to happen or not, let's look at where were the stories of Matt, Karen, Fisk and the rest of the survivors, as well as those who did not live to see justice prevail.
Elden Henson's Foggy Nelson took a step forward in season 3, in terms of guiding his own destiny. His public persona exploded after his grand speech against the establishment went viral. He also used the power of the Internet to broadcast the video of Agent Nadeem's phone, thus giving everyone the proof of Wilson Fisk's conspiratorial crimes. Way to spread that word, Foggy!
The spectators also had to spend some time with the rest of Foggy's extended family for a while, which made it a magical moment within this universe. Especially when alcohol was involved. While we are pumped that Reckless ended season 3 by making "Nelson, Murdock and Page" a reality, it would also be great if all the members of Foggy's family also joined the firm and constantly helped in the office.
Throughout season 3, Karen's current story is not the most complicated issue. Initially, he set out to prove that Matt survived the implosion of the Midland Tower, and later set a gigantic goal by admitting to Wilson Fisk that he had murdered his former footman James Wesley. He helped a group of people escape Proto-Bullseye's anger within the church, and seemed ready to join the body of the deadly villain. However, Deborah Ann Woll excelled in showing more to Karen's viewers in the character's tragic blended episode (which should have been a mid-season bow).
Before entering the world of journalism with the infusion of vigilantes, Karen was caught in a drugged spiral trying to keep the family diner intact after the death of her mother. Terrible decisions were made, and an intoxicated Karen ended up killing her idealistic younger brother in a car accident, after he shot his abusive merchant boyfriend. Was much get into 3/4 of a single episode, but definitely gave the character a meatier subtext that informed his place within these series. Here she is waiting for her research reporting skills to take her to The Punisher Season 2.
For so many years, Father Lantom by Peter McRobbie was one of the most important and trusted people in Matt's life. Naturally, everything turned upside down in Season 3 when Matt involuntarily reconnected with his mother Margaret, better known by others as Sister Maggie. Matt's faith in God's plan was already waning in the first episodes, and his faith in Father Lantom was broken after Maggie's maternal turn was revealed.
With that emotional crossroads between them, Matt and Lantom's relationship was completed in the most tragic way possible. During the attack disguised as Dex Poindexter in the church, Father Lantom witnessed first-hand the lethal accuracy of the villain, although he did not live long enough to tell anyone about it. However, he did ask for Matt's forgiveness, and Man without fear granted it.
