Tattoo says it all

So season 6 begins with an eye shot of Jack laying on his back in a forest……..pans out and it is shot by shot the beginning of season one……..Loop has gone its full cycle……..So here we go again……….could be the 2nd time perhaps the 27th time……that doesn’t matter……….however with each loop begins subtleties change……….the phrase “you were not meant to do this” is peppered through out……….thus rules that are broken. …….solid rules like ending ones life, in which never happened the previous loop (or did it ) ……..depends on ones perception…………anyways back to our loop………..the one we will watch unfold on T.V…….So this time around something huge has changed……………”walks among us, but is not one of us” Jacks tattoo……….How convenient………….it just so happens…..Jacob has found his loop hole…………and considering it is the past ( previous to his death) he is very much alive………..so now we still have John vs Jack………black vs white………Jacob vs Nemesis……..but the tables are turned……….Jacob has the upper hand now…….he is much further in the past than when Nemesis takes John as host………..Now the question is where on this time line does Jacob ala Jack step into this time line to save him self……..
