Every once in a while, there is a great moment or battle that really changes the course of history.  The Battle of Salamis, Caesar crossing the Rubicon, Charles the Hammer winning the Battle of Tours, The Battle of Hastings in 1066, Luther nailing the 95 theses to the door in Wittenberg, the assassination of Archduke Francis Ferdinand, the time I defeated my neighborhood HOA by installing a whole pallet of grass sod in my front yard even before they mailed me a nasty letter.  I got other nasty HOA letters, but not about the front yard grass. All of those were key moments that changed the direction of history in some way.  They turned the tide, so to speak.  

And this episode is one of those moments.  And, as a quick spoiler, next episode will be one, too.
