Fate/Free will-Update

I got an idea to describe Billy's fate in class, so I thought I would share it. When a cocunut falls from its tree into the ocean (so the tree lets go of its fruit), then which river it will go in, which land the fruit will be planted on to pulp a new tree (and even if it is lucky enough to survive), is completely dependent on the fruit and its destiny. This is fate. Similar, to this is Bily's case. Fate carries Billy from one time spectrum to the other.
