With Silas dead,Klaus gone to "semi-protagonist/antagonist thing",I mean he has no motive to kill Elena and the others,who will be the main one? I don't see them pulling another rabbit from the hat,I mean first it was the legendary Klaus,the entire Mikaelson family too,then they are gone,next one was the other "super-legend" Silas. What can they think of to end the series? I don't see them bringing another "legendary" one and one weaker that much from Klaus and Silas for example isn't just fit enough for final villain. Your thoughts?
