All Shook Up, Version Two

In this version, Marie Renaud jumps to a parallel Earth, just in time to rescue Elvis from dying of a heart attack on the toilet. She nearly dies in the attempt. Both Marie and Elvis are saved by Erin. Marie is the only operative who has learned how to time jump, and she jumps back to Alpha Earth in the year 1977. Erin returns to find subtle changes in the world he left.
The last scene occurs in 1981. Elvis is performing at a festival with Willie Nelson and Waylon Jennings. Erin's mother is allowed backstage to meet Elvis. Elvis apologizes to Erin's mother, saying he doesn't usually mix with young girls on the road, but in this case, he'll make an exception. Marie introduces herself to Erin's mother.
