In the penultimate episode for the series, we get a cold opening scene of Yelena's blip and return. She breaks into Kate's apartment to have a heart-to-heart talk while also informing Kate that she is Natasha's sister and plans to kill Clint. Clint arranges a meeting with Echo and reveals himself to her as Ronin, providing her with information about who hired him to kill her father. Yelena reveals to Kate who contracted her to kill Clint, and sends Kate a photo of her mother meeting with the notorious Kingpin (Vincent D'Onofrio, confirming that his character from the Netflix show Daredevil is indeed canon in the MCU). As Mike says, Kingpin confirmed!
