This was a recap episode with nothing new basically. Clips from the first season and narration to explain things and introduce all the characters. It didn't explain what's going to happen in this season (or version, whatever it is) nor what is the initial setting. Although, if it's going to tell a different version of the story, I fail to see why the audience was reminded of every character like this. My wits tell me the story should continue after a recap, not rewind to the beginning and tell it anew.
It has been a while since the series ended so maybe a recap was in order, but still it afterwards feels like a wasted episode, of course.
