In alternate realities, small changes lead to dramatically different outcomes. For example, Bilbo left his mithril shirt at Michael Delving, therefore Frodo wasn't wearing the Elven armour when they met up with the cave troll in Moria, hence Frodo kicked the bucket and the ring passed to...who? Aragorn would not take it, neither would Gandalf; Gimli would never let Legolas take it, and Legolas would not see the dwarf take it. Gandalf would never trust Merry and especially not Pippin, so the ring would, therefore, go to Sam. Sam, being the truehearted and quite stubborn hobbit, would unwillingly take the ring and become the ring bearer. When the Grey Istari falls into the deep places of Moria, Aragorn will lead the fellowship of seven to Lothlorien... but what will be the reaction of Samwise Gamgee to Galadriel's mirror? What will he see... his Gaffer being kicked out of his home and the Shire on fire? Will he see the eye of Sauron in the waters? When they leave Lorien, will Sam choose to go to Minas Tirith or to Mordor? Sam, although he doesn't trust the son of Denethor, will consent to go to Gondor... but what happens when the Uruk-hai attack? As you may assume, in each reality a different choice is made and a different outcome occurs. In some realities the quest will be successful, in others Sauron or Saruman or even Denethor will take the One Ring, it all depends on choices. These decisions we make in our everyday lives can alter the outcome of our fate... an example is this: You go out partying with friends, in one reality you drive yourself home, in the other you take a cab. In one you die, in one you go home and wake up with a killer hangover and angry parents for breaking curfew. Small choices make big differences.
