They both ended up at the hospital and both Jeff and Jenny become 90 second old newborns both not wearing any diapers, each the Cords sticking out, and both being held by a Mom which they will become a pair of twins. The Chronivac starts to countdown for 90 seconds to their Unbirth. 89... 88... 87...
Each of the cords gets Connected to the placenta which where the womb and the womb sacs came from inside through her vagina. Jeff and Jenny are now 50 seconds old. The Chronivac beeps as Jeff is now being regressed faster from 10 seconds each. A Doctor grabs newborn Jeff who is now 30 seconds... 20 seconds... 10 seconds. The Mother then starts to pull him in from his head to the vagina and then his torso and then his legs through the vagina. Only his butt and penis is show being pulling back inside to the womb. "Jeff Age Status; Fetus, 9 Months." Said the Chronivac voice.
Next is Jenny who is 15 seconds old. The Doctor helps the mother pull her as well from legs first. Then her arms and her torso. Her head is sticking out as she gets pulled inch by inch until she goes back into the womb. "Jenny Age Status; Fetus, 9 Months." Said the Chronivac voice. Now both Jeff and Jenny are finally happy inside their new mother's womb. Now all they hear is the heartbeat of a new mom.
