Because no funeral that Endgame would have been able to show would have lived up to the one we can now imagine, knowing what we know after Natasha's standalone. Nat's funeral wouldn't have been a respectful private gathering, it would have been an international event.
"Scarlett talked to me about it: Her character would have hated a public funeral," Shortland told Variety about Natasha's modest gravesite in Ohio. "So I felt like the fact that she's buried in a really private place, in the boondocks somewhere, is perfect."
Originally Answered: Why doesn't Black Widow have a funeral or memorial in Endgame? She can't have a funeral because her body is on Vormir when she sacrificed herself for the Soul Stone.
Black Widow was part of the Time Heist team in Avengers: Endgame, but in order for her and Hawkeye (Jeremy Renner) to get the Soul Stone from Red Skull in Vormir, she sacrificed herself.
As Shortland explains... In Endgame, the fans were upset that Natasha did not have a funeral. Whereas Scarlett, when I spoke to her about it, said Natasha wouldn't have wanted a funeral.
Why Black Widow didn't get a Funeral Finally Explained [POSSIBLE BLACK WIDOW SPOILERS]
Is Black Widow dead for good?
Black Widow sadly gave up her life to save others in Avengers: Endgame, and Hawkeye gave even more meaning to her Marvel Cinematic Universe death. In Hawkeye, Clint Barton's holiday plans with his kids get upended when Kate Bishop (Hailee Steinfeld) started wearing his old Ronin outfit while fighting criminals.
By the end of the film, Yelena is so devastated by Natasha's death, that she's willing to listen to Val—a stranger—when she tells her that Clint Barton is responsible for Black Widow's demise (which occurred in Avengers: Endgame).
Gamora was sacrificed by Thanos in the Infinity Timeline. Bc they went back to multiple dates before Thanos could even get to the stones, he never got to the point of sacrificing her for the soul stone, because Clint and Natasha went there first. So, Natasha simply ceased to exist in the original End Game timeline.
Is Black Widow alive if the Soul Stone is returned?
In the end of Endgame, Captain America had to return the Soul Stone, but did that revive Black Widow? No. Red Skull does not say that returning the stone could revive the dead people. Gamora and Black Widow are still dead, and their heads were bleeding.
Hulk couldn't bring her back because you can't use the power of the stones to resurrect her as the exchange is permanent, but when Cap goes back to return the stone he could exchange the stone back for her soul.
If Natasha hadn't sacrificed herself on Vormir to bring everyone back, she would've joined her family in order to free every Black Widow in the world. After all, this was also a personal cause for her and, after the Battle of Earth, she would've had some free time.
Natasha chose to be the sacrifice and so, Romanoff was 39 years old when she died, but the time travel in Avengers: Endgame creates a little bit of a complication. Romanoff and Barton used the Quantum Realm to journey back to 2014 so they could beat Thanos (Josh Brolin) to the Soul Stone by 4 years.
Robert Downey Jr. confirmed that Iron Man 4 is indeed in the works. While negotiations continue for his return, this would mark his 7th appearance in a standalone Marvel movie and his 9th outing as Tony Stark in total.
Whose grave was at the end of the Black Widow movie?
We don't know how much time has passed, aside from it being post-Endgame, and we don't know if Yelena was dusted or not. But here, Yelena and her dog, Fanny (a little nod to Natasha's alias from earlier in Black Widow, given to her by O-T Fagbenle's Mason), take a breath to mourn Natasha, a “daughter, sister, Avenger.”
“It's not the Gamora that was killed by the Soul Stone, that is the Gamora from the past. When Gamora went off that cliff, the Gamora from that time period died. But this is the Gamora from prior to that. So she's still alive, she traveled in the time machine to the present.
Although, for the Black Widow star, it seems very unlikely. In an interview on the Today Show, Johansson addressed recent rumors about a future appearance as Black Widow in the MCU: "I think it might be... I think it was the end, right?
Did Black Widow sacrifice herself for the soul stone?
Avengers: Endgame saw Black Widow giving her own life in order to help the heroes obtain the Soul Stone. Should it have been Hawkeye who died, though? The MCU's Avengers: Endgame had a Herculean task; to complete the story arc from Avengers: Infinity War and do it in a way that satisfied fans.
The threequel revealed that 2014-Gamora had gone on to join the Ravagers since the events of Endgame. She acts as though she doesn't know Peter and the Guardians because she really doesn't – this Gamora isn't the Gamora we watched in the first two Guardians movies.
Because she does not have a history with the Guardians, she does not reunite with them at the end of Endgame. Instead, she starts her own journey while Peter Quill is left mourning his dead girlfriend despite the existence of another version of Gamora in his universe.
Probing Nebula's cybernetic memory banks, Thanos' suspicions were confirmed, that Gamora knew of the Soul Stone's location and had secretly admitted it to Nebula. Having decided to move further in his quest, Thanos lured the Guardians of the Galaxy to Knowhere where he took the Reality Stone, and ambushed them.
Back to Hulk's snap, Tony reminded him that he had to bring back those who vanished after Thanos' snap but without changing anything from the last five years, and he did so, but he also tried to bring Natasha back.
So there you have it. After we last saw Yelena in “Black Widow,” she spent her time freeing other black widows from mind control, got snapped out of existence, and then began working as a contract killer for Valentina – which is how she got assigned to take out Hawkeye.
However, Red Skull told Hawkeye that Black Widow's death is permanent. Later, the Hulk (Mark Ruffalo) says that he tried to wish Black Widow back into existence when he held the Infinity Stones, but that it wasn't possible because, as Red Skull confirmed, the magic of the Soul Stone requires a permanent sacrifice.
