Wilson Fisk's MCU debut (or return depending on how you choose to look at it) in Hawkeye broke the internet back in 2021. Revealed as New York's Kingpin of Crime, the villain's role in the death of Maya Lopez's father led to his "niece" gunning him down in an alleyway.
Despite being left for dead, Fisk managed to survive that bullet to his head and returned in Echo today. We first see him at the end of the premiere when the bandaged baddie wakes up in a hospital bed after seemingly laying comatose since that clash with Maya.
In the third episode, some of the Kingpin's men arrive in Oklahoma to take her out - Maya has spent months fending off his goons - only for the ringleader to receive a call from his boss which gives her a stay of execution. During its closing moments, a very much awake Fisk arrives at Maya's old family home wearing an eyepatch and bandage; in case it wasn't clear, he "saved" her.
A full explanation for how he lived is never given (his apparent power upgrade in Hawkeye led to speculation he might have taken Power Broker's Super Soldier Serum), but the eyepatch does have a power source which is presumably healing his wound and looks to even be growing back his eye.
Again, it's never explicitly stated, but Daredevil: Born Again set photos haven't shown Vincent D'Onofrio with any noticeable scarring. Remember, this is the MCU we're talking about so the technology is likely there for him to have fully recovered by the time that series starts.
After pleading with Maya to rejoin his organisation and even presenting her with the same hammer from Daredevil we saw him use to kill his father as a child, The Kingpin loses it when she rejects him. As a result, he enacts a plan to kill Maya's friends, family, and people during the Choctaw Powwow.
She confronts him - we'll take a deep dive into her powers later today - and uses her newfound abilities to not fight The Kingpin, but heal him instead. Taken back to his childhood bedroom in a vision, Fisk attempts to fight off Echo's attempts to heal the pain and rage he feels by moving on from his traumatic childhood (earlier in the episode, Fisk suggests she "free" him by using that same hammer).
The process seems to work to some extent, but The Kingpin is by no means. In fact, aboard his private jet, he demands all the different crime bosses meet to sort out a problem which is spiralling out of control - Daredevil's repeated attempts to take them down, perhaps? - and appears to then embrace the idea of running for New York City Mayor after watching a news report.
Some part of him might have healed and moved on (and Maya's powers might be what physically fixes him), but it looks a lot like that will translate into The Kingpin believing the right thing to do is to take on a legitimate position of power to fix his city...all while removing those who stand in the way of his criminal enterprises. That's not good news for 'ol Hornhead...
