Just a note — When I watched “Black Widow” in a prerelease screening, the post-credits scenes were aired back to back. In normal Marvel films, one scene will air after the first round of credits (which often feature a logo and a list of the main actors) and a second scene will air after the full credits roll.
‘Black Widow’ leads into ‘Civil War’ ending and ‘Infinity War’
The first end-credits scene begins when Black Widow — now with the blonde hairstyle she has in “Avengers: Infinity War” — meets with her old friend, Rick Mason (O-T Fagbenle). He shows her that he’s given her a new ship — one that you might recognize as the new Avengers Quinjet, which was seen in “Avengers: Infinity War.”
Black Widow then says she has to go repair the damage of her other family — the Avengers — and break the Avengers out of prison. This is a nod to the “Captain America: Civil War” end scene, where we see the Avengers, recently arrested by the government, being broken out of prison.
‘Black Widow’ teases the future of the Marvel Cinematic Universe
The second post-credits scene will leave some fans shocked. My jaw actually dropped when I watched this scene, so be warned that there might be some shock.
The second post-credits scene shows Yelena (Florence Pugh) visiting the gravestone of Natasha/Black Widow (Scarlett Johansson). This takes place after the events of “Avengers: Endgame,” in which Black Widow sacrificed herself so the Avengers could nab the Soul Stone.
The heart-wrenching moment is cut short, though, as Julia Louis-Dreyfus sneezes from the side of the screen. She then exchanges some dialogue with Yelena, and it’s hinted that Yelena is working for Dreyfus’ character.
Then, Louis-Dreyfus’ character hands Yelena a piece of paper that shows Hawkeye (Jeremy Renner). Louis-Dreyfus says that Hawkeye is responsible for the death of Natasha.
Marvel fans will recognize Louis-Dreyfus as Valentina Allegra de Fontaine, who first appeared in “The Falcon and the Winter Soldier.” She was influential in encouraging John Walker (Wyatt Russell) to suit up again in a black Captain America suit. She said the world is about to get weird, and the U.S. will soon need a U.S. agent and not a Captain America.
