So far, I've been less impressed by the series as time goes by.
The story of Dawn and his escape from the castle, may have been the first interesting development in the series.
For one, it provided a backstory for Azura, who clearly 'knew too much' for a run of the mill gardener and this pretty much seals that angle.
And then, despite the whole failed subterfuge of planting an Agent Provocateur in the Palace as Dawn's replacement, ala 'Man In The Iron Mask', Day's return from the Spiral ordeal may change how he deals with a Dawn, who's not so perfectly cloned, as Day's experienced something which the prior Cleons before him never tried.
For me, this was more interesting than Hari's AI leading a Motley Crue towards the Invictus, a conclusion which was almost predictable from the middle of the series when we discovered that Hari had himself uploaded prior to death. It was just a matter of time before such an AI would emerge from the vault & since the episode's titled 'The First Crisis', it only follows.
