We also meet Melina Vostokoff — but does that mean Melina is the Iron Maiden?
We see Melina Vostokoff (played by Rachel Weisz) sitting at the table with Natasha, Yelena, and
David Harbour the Red Guardian, where she informs him he’s gotten fat. But according to some comic book research, Melina Vostokoff is actually Iron Maiden, a supervillain who notoriously wants to take Black Widow down. Iron Maiden was originally an assassin for the Russian government where she was under orders to kill Black Widow, until S.H.I.E.L.D. stepped in.
