Seifer and Squall are brothers

[McLovin']

By looking at the characters interactions one realize the following:

Edea and Seifer are Rinoa´s parents.
Squall and Rinoa are Zell´s parents.
Zell and Quistis are Selphie´s parents.
Selphie probably stays with Irvine.

This looks crazy but it´s not because the world of FF8 is a "time compressed" world comprised of about 6 eras.
Evidence?
I made a lot of threads in the past showing them.

But you can do the following experiment:
Divide the world in 6 big areas so that you can´t cross between them on foot.
Then take the Ragnarok to different places and try to realise how these places evolve from one place to the other.

what's the purpose of that though in regards to the story though?
