The Ending Of Marvel's Echo, Explained

"Echo" takes place directly after the events of "Hawkeye," in which Maya Lopez learns from Clint Barton that, as Ronin, he was anonymously hired by Kingpin to assassinate her father and several other members of the Tracksuit Mafia. Maya subsequently leaves Kingpin's organization and confronts her former friend Kazi Kazimierczak (Fra Fee), killing him during the Tracksuit Mafia's battle against Clint and Kate Bishop. She later ambushes Fisk and shoots him, presumably putting an end to New York City's greatest gangster.

This is where "Echo" picks up, with Maya returning to her hometown of Tamaha, Oklahoma to take over Fisk's operations there. She locks horns with her uncle Henry (Chaske Spencer), who, like Maya's father, was involved with Kingpin's organization against his will. After attracting unwanted attention from the Kingpin's henchmen, Maya discovers that Fisk is alive, and he offers her a chance to return to New York and resume operations as his "Queenpin." 

Throughout all of this, Maya is also battling recurring visions of her ancestors, including the first Choctaw woman, Chafa, as well as Tuklo, a Choctaw warrior from the 1800s. She's also confronting her strained relationships with her family members, including her cousin Bonnie (Devery Jacobs), whom she avoided contact with following her father's death, and her grandmother Chula (Tantoo Cardinal), whose anger towards Maya's father left them estranged.
