Ok, let's see.
Peggysous: Peggy moves on from a crush, falls in love with Daniel, has her family, holds dear Steve's memories because she respected him. It wouldn't change all the issues her SHIELD arc has but at least it wouldn't really affect the personality she was given-

EGst*ggy: the skrull goes to her in 1949, 4y later 1945Steve crashed in the Artic, so now she is dealing with a much older 2023Skrull. If it's an alt-tl and she doesn't see he's different, it makes her stupid. If she sees it but is ok with him playing god with her-

- life and the lives of billions all for a missed date, it makes her a villain like he already is. If it's a timeloop and they spent their lives hiding Steve and lying and just looking at all the atrocities unfolding under their eyes it's the most unhealthy story ever, if they-

- aren't perturbed by it, they are both morally wrong. There's also 1945Steve still iced in the Arctic but who cares?If you are ok with the two Steves taking turns I don't know what it says about you. If you think Peggy would choose 2023Steve over 1945Steve could you explain-

- why? What do all these outcomes say about her? How is her personality affected? Do you really think it's the same as Peggysous? In the alt-tl her life could be radically changed. But yes, keep saying that ships don't matter and that they don't influence the characters' arcs...
