Remember Robin Arryn? The kid who was never weaned off of Lisa Arryn in the earlier seasons of 'Game Of Thrones'? Here's a little background on this kid in case you've forgotten: Jon Arryn was like a father to Rob Stark and was the Hand of the King to Robert Baratheon. Upon his death, Catelyn receives a letter that says that Jon Arryn was murdered. 

This leads Ned to leave everything and head South to help Robert with his falling kingdom. This was the initial conflict on 'Game Of Thrones' which lead to the domino effect of chaotic events and thousands of gruesome deaths that lead us to where we are today.

And lastly, arguably the only good thing that came out of this episode.

The only thing I will take away from any of that is that #robinarryn grew up damn fine #TheFinalEpisode
