The Woman in the Red Dress (Howard and Maria Stark One-Shot-- AU)

When part of the Avengers are thrown back in time find the Soul Stone, they encounter the wild truth about the what was SHIELD. A woman in a red dress takes them hostage, and their only hope is to be saved by Agent Carter and Howard and Maria Stark. During all of this, Thanos has followed them back, hoping to get into the Infinity Stone before anyone else, even if this means death.

Legally, I do not own any of the characters or whatever.
Note: I will state now that it will not all be correct, and in some aspects, I am glossing over things as well as rewriting events. I am focusing more on the movies and a little on "Agents of Shield." I do not mean to do this entirely, however to further the plot, it was necessary. I hope you can understand. Also, obviously, this does not follow "Infinity Wars" plot because it was written and published before "Infinity Wars" came out.
This will written because I was sick and tired of Maria Stark having no backstory and was constantly there to further the plot points of males around her, in the comics and in the movies. While this is fictional and not based much on her character, I did try to keep it as close to the material I was able to find online as possible.
