The latest “Black Widow” solo movie trailer featured an interesting bit where Rachel Weisz’s Melina is referred to as Natasha’s “mother.” Previous trailers showed Scarlet Johansson’s avengers calling Florence Pugh’s Yelena “sis.” So are they actually family?

The short answer is not by blood or law, but much like the Avengers, this is a chosen family. “Black Widow” will reveal that the women, along with David Harbour’s Alexei, function as a family unit because they had to go undercover as such. Entertainment Weekly’s Scarlet Johansson cover story reveals that Natasha Romanoff turns to her surrogate parents and sister after going on the run at the end of “Captain America: Civil War.”

“She turns to the only other kin she’s ever had: a hodgepodge band of Russian spies who went undercover together as a family when Natasha was a child,” EW reveals.

Seemingly, that indicates that the Marvel Cinematic Universe (MCU) movie will give viewers a better idea of exactly how young she was when she started in the Black Widow program. At the very least, viewers will understand how their oddball family works.

The final trailer makes it clear that they have a strong bond. Yelena Belova reveals that she tells people her sister has moved out west, is teaching science and has a husband who renovates houses. Marvel fans know that this can all be connected to Nat’s real life.

Black Widow is largely based in the U.S., and she seems to at least be knowledgeable about science, revealing in “Avengers: Endgame” that she has read about quantum physics “only to make conversation.” Plus, she teaches the new Avengers like Wanda Maximoff/Scarlet Witch (Elizabeth Olsen), and Clint Barton/Hawkeye (Jeremy Renner), who is basically her work husband, had a mild obsession with renovating his house in “Avengers: Age of Ultron.” It seems like Yelena knows her sister well.

The familial aspect of "Black Widow" was surprising to the cast. Most of the new actors likely signed on without reading the script, which is typical for a Marvel Studios movie. “I thought it would be a straightforward action movie, and then it wound up being a real character study of a dysfunctional family,” Harbour told EW.

“Black Widow” hits theaters May 1.
