Maybe you’d like a shot at the man responsible for your sister’s death.
The end credits scene has Yelena visiting Natasha’s grave after Avengers: Endgame, and being recruited by Valentina Allegra de Fontaine for a mission to kill Clint Barton.
The look of this location appears to be the Golden Oak Ranch in Santa Clarita, CA. While some sites have claimed that this is the Myrtle Hill Cemetery in Rome, GA near where some of the Ohio scenes were filmed, it doesn’t really look anything like the cemetery seen here. So, I’m not calling this 100% confirmed, but it’s a good hunch that this is at least in the Santa Clarita area.
