There's nothing quite like being frozen in a block of ice to ruin a relationship. With Steve Rogers being perfectly preserved for decades in the world's largest natural refrigerator, S.H.I.E.L.D. Agent Peggy Carter continued to grow older and even got married though it was obvious that Steve remained the love of her life. When Steve was defrosted, the first thing on his mind was Peggy. However, a few films later, Steve is making out with Peggy's niece just a few hours after his first love's funeral.
Here's what Peggy would think about that, according to Hayley Atwell [via IGN]. "Well, first of all she'd be turning over in her grave. She'd be like 'no.' And she'd inject herself with the blue serum and become a super villain. She'd break out of her coffin and ground [Sharon]. She'd ground her. Then she'd kick Steve's ass as well. 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!"
Hayley even showed her awareness of what's happening on the comic side of the business, citing the current shocker that Steve has been a Hydra Agent all along. "[Peggy would] want the best for her [niece] and she'd want her dating a good guy. And now with this whole 'Hail Hydra' business, I don't know if Steve's good enough for her. So on all levels, it's just a big fat no."
