Certainly unlike any other episode of this series (besides the pilot perhaps), introducing new characters and intertwining them with the main characters perfectly like this show always does with the past, present and future. Great writing and an intriguing look at what is to come for this show. I thought season 3 was a bit on the weaker side, especially compared to the first two seasons. Looks like this season will definitely be something special and I can't wait to see what comes next.
