For seven seasons, Rick and Morty viewers have wondered what happened to Rick's wife. Why is she absent from any reality? Why is Rick himself obsessed with revenge? And the answer is scarier than any theory. Rick Prime, the hero's worst enemy, destroyed Diana with the Omega Device, erasing all versions of her from all dimensions. She disappeared from the very fabric of reality — not dead, but nullified, as if she had never existed.
That's why Rick can't bring her back, can't meet her in another universe, can't even try to forget — because all the pain is left only in him. He remembers her alone. All he has left is an artificial voice on the ship, a couple of false memories and emptiness.
The death of his wife and daughter pushed him onto the path of madness, revenge and loneliness. But now that he has defeated Rick Prime, the hardest part comes: living on, knowing that even an infinite multiverse could not save the woman most important to him.
