Simple. It all happened when Kahmelon was over while I was playing FFVII...I said something about how Sephy liked to cook garlic mashed potatoes...and well....turns out everything can be linked to the garlic mashed potato. Example.

Sephiroth stays in the Shinra mansion basement- Looking for a recipie for Garlic Mashed Potatoes.
Sephiroth burns down Neibelheim- They didn't like his Garlic Mashed Potatoes
Shinra kidnaps Aeris- They want her Garlic Mashed Potato recipie
Vincent falls in love with Lucrecia- She made damn good Garlic Mashed Potatoes
Hojo shoots Vincent- Vincent forgot to save some Garlic Mashed Potatoes for him
Sephiroth kills Aeris- She claimed that his Garlic Mashed Potato recipie was her own. Bitch
Tifa's boobs- She stuffs with Garlic Mashed Potatoes
Vincent stays somewhat distanced from the group- The group has a lot of garlic mashed potatoes and because Vincent's a vampi...I AM NOT A VAMPIRE!...fine...scratch that....
Cid stops the rocket- Wasn't because of Shera. It was because he didn't have any freeze dried Garlic Mashed Potatoes
