In the world of superheroes, because it’s such a melodramatic world with operatic undertones to it, most of the best ones have some sort of tragedy, deformity, or disability that is meant to add depth and poignancy to their heroism, whether that’s Bruce Wayne sobbing over his parents’ bodies or Bruce Banner forced to live a life of emotional repression in order to keep his dark side at bay. You could argue that Peggy’s cross to bear is Steve’s death, but we’d argue right back that she’s mourning him in a more or less normal, human way and her grief seems to be following a healthy evolution. No vows to dress like a flying rat over his grave or anything. She’s just taken what she’s learned from him and letting his memory inspire her. No, her cross is even more basic than that. In order to protect her mission from her co-workers, Peggy has to become the bumbling, ineffective Clark Kent/Peter Parker type, hiding her victories and strength from the very people she so desperately wants to notice them. And because this show is using the patriarchal and chauvinistic attitudes of the day as a backdrop for this story, Peggy’s sacrifice becomes all that much more poignant. She has to pretend to be dumber than she is and take no credit for her work in front of a group of men who already think it’s an insult that she be allowed to work alongside them at all. Peggy Carter’s kryptonite IS the patriarchy.
