Natasha: No matter what you do to me! I’m through serving your evil schemes!
Khrushchev: I thought you might react that way! And so, I took the liberty of bringing your parents here! If you have no fear for yourself, surely you don’t want the state to treat them as parents of a— traitor!
Natasha: Mother! Father! Oh, no!
Father: Do not fear for us, my daughter! Do what you feel is right!
Natasha: But I could not let any harm befall my parents! And so…
Natasha: And the warmth of my parents— my… parents… makes up for… no… no, that’s not right…
The classic Black Widow children’s story is Daredevil #88: in the hollows of Stalingrad, 1943, a soldier looking for his dead sister finds an orphan girl in the ruins. But before that issue, when she was bad Natasha had these nameless parents, that her masters threatened to keep her stick straight. This 1965 scene was the first hint at Natasha’s inevitable defection. Strangely, she never thought of her parents again, even after she left the Soviets for keeps. Even though at one point they’d been all that was keeping her for leaving. Then her backstory became something else, and it was easy to drift over this panel. Maybe Natasha had been lying about her change of heart, and about her parents. She’d lied to Hawkeye before.
Several retcons later, Paul Cornell and John Paul Leon wrapped it back into Natasha’s tangled history. Her parents weren’t real, but she thought they were, for a while. Notice how bit from Black Widow: Deadly Origins #2 clearly references Tales of Suspense #64.
