Mostly a hell of a lot of set-up for next episode. Aside from seeing how all the pieces fall together and how plans are outlined regarding what's going to be the final battle of this season, we also get some more insight into Mireille and Thomas' backstories. That part was my favourite, just because we got to see the development of them both which can contextualise their current feelings and ways of living. As for the set-up, it was done in a way that felt a little tedious to me, but I think it'll have good payoff - or, at least, I hope so.
