Ayra's scene was 6 years coming.
The beauty of it was you already saw what happened to him, this time you the viewer were "in" on it in complete dramatic opposition to the red wedding.
I though it was a master stroke of storying telling. Great use of dramatic irony to remind you that the Ayra (and most of the Starks) has always been portrayed from the viewers perpective, she never had secreats from the viewer or been used for dramamtic irony, or pull back/reveals. She didn't "go missing and suddenly show up" we've been seeing her viewpoint the whole time and now finally she's the one with the effecting the world, and not vice versa, and we're in there with her, as we are with brandon, Jon, Sansa, etc.
