It is been 9 months from now. Antonio became an egg with cells inside merging together. Antonio has gone back on conception now.
Outside, Penny and Rick are going to make out inside a blanket.
Back inside, the Egg is now trying to separate itself. Then, the Egg and Sperm became separated. That is when The sperms goes in to swim backwards as the egg then rolls backwards too. The sperms swims backwards even more until it reaches into Rick's "Stick" as it sucks it all up inside. Meanwhile, the Egg has been sent back into her Ovaries.
Antonio is No More. And now he does not exist in this backwards world anymore, there is only his mom and dad. But... Who will focus on first?
