Great writeup of this latest season and how it continues to push the shows narrative forward, but it basically spoils the entire season so don't read if you have any interest in watching the show but haven't gotten around to it yet.
Finished watching season 4 last night. Episode 11, "Times Arrow" was the best episode of the season, hands down.
Happy ending? Did they not see the scene right before the final scene?
Holy shit, this post should have a big spoiler tag.
