1.Persehone returns to the earth in Spring
Demeter:Thank god you cam back!
Persephone:Hi mom, it was awful. Finally I ate some food but only seven pomegranate seeds.
Demeter:Oh no! Why, that means you need to stay seven months in the underworld.
Hades: my plan did not work completely.She only ate seven seeds which means she could only stay with me for only seven months. Why not forever!!!!!
