If you thought last week's episode killed the pace, get your remote control handy.
This part monologue, part narrated story is an exercise in self indulgence that shines a spotlight on a few loose ends from the novel , to no good effect and adding nothing to the central plot.
In a longer or tighter story it might have served some purpose to set aside an episode to tell it's own story (this was done to good effect in The Last of Us) but the series was already meandering before it curdled in this stagnant backwater episode.
For a story which is at heart about the power of stories to get the telling of a tale so tragically wrong is somewhat ironic.
