Game of Thrones Season 6 has been one of returns: people coming back to life, characters not seen in years coming back, and storylines circling back round in places like the North and Vaes Dothrak.
That theme is continued to The Broken Man, which delivers probably the biggest return yet (because everyone knew Jon was going to be resurrected, but this was less certain, although heavily theorised).
There has also been a current of change running throughout, and the return of this episode (I'll not mention it in the intro, just incase you've stumbled here by some happy accident) ties in with that. The person is trying to change, but it's not as easy as it seems. Meanwhile, Arya has refused to change, and is facing up to the consequences of that, and Margaery's saying she has. Theon was forced to change, and now he's being forced to change back.
Following on from Blood of my Blood, this was another quiet episode, but the show has moved all its pieces into place to really let loose in the final few episodes. And after The Broken Man, the payoff should really be worth it. It wasn't an absolutely great episode, but it was still a good one, with a couple of particularly big moments.
