"Well, first of all she'd be turning over in her grave," Atwell replied. (The article noted that she did so "with a grin," however.) "She'd be like 'no.' And she'd inject herself with the blue serum and become a supervillain. She'd break out of her coffin and ground [Sharon]. She'd ground her. Then she'd kick Steve's ass as well."

The actor is far from the only person to feel unconvinced by the romantic development between the two characters; fan outrage towards this moment in Civil War proved to be one of the main motivators behind the recent #GiveCapABoyfriend social media movement, with many complaining about Steve moving in on the great-niece of his former flame just days after her death.

Atwell continued, "I just feel that, you know — I wouldn't want to date my great aunt's guy. It just feels like it crosses an incestuous boundary. And Peggy just died. That's even more disrespectful, right? It's like, 'don't touch that."' You can't tap that!"

The Peggy/Cap/Sharon romantic triangle isn't a new development, however; Cap's relationships with both Peggy and Sharon Carter come from comic book canon, where the shifting nature of comic book aging mean that it has an additional layer of confusion: Sharon was initially Peggy's younger sister before later being retconned into her niece.
