With him was only the pain of the loss he wasn't able to prevent.
Above him was heaven, the cold illusion of a pure and hopeful world.
Left and right seemed to be only detours to a destination, which has been settled long before they came into their path.

Where should he go, if pain, emptiness and isolation were the only ones waiting for him?
The only possible way led downward,
and Castiel realized.
Angels fall since Angels are not allowed to love.
