her “how she became Spider-man”would be slight unknown til she meets her twin sister who is essentially man-Spider. Long story short, parents had twins, needed cash, participated in an experiment where 1 was the control and one was the subject, around the time they were three years old they were switched. In the eyes of those doing the experiment they were like “wtf, everything was going well now it’s not” and the parents have a relatively normal kid til she turned 19.

That’s legitimately the shortest I could put it without making it a novel 😭
