finished all in 3 days. it will be 5/5 if season 4 end in episode 9, and it continous with another season where john lead the GNR (slowly start to separated from Berlin) with a fixed "nazi's broken system" because we all know that he knew there are a lot things wrong and he has the chance to change it. he is a strong leader, he had been the foundation of all things that happened since the beginning, it will be so much better when he didnt kill himself. close the gate, he will use the information he already had from the other world as a lesson for him to change his world to a better one. the resistance generally might wont stand on his side, but juliana will. she seen the other version of john in other world, he saved her. its a key, a sign, or as we call it invisible string that show who john smith really is
