So that they can give Prime Dolores a dramatic death in the "finale," only to have it turn out that "shocker!! Remember we said there was another host created after they escaped WW? She's ALIIIIVE!"
Can't Maeve control Dolores? Or does she just like keeping her alive so she can fight her personally? (And if not, I echo the previous poster who asked why she didn't take control of D's rifle and/or drone).
This season has really just been bad, IMO. It doesn't feel like Nolan or Joy's writing or even vision. The dialogue and plotting is pretty bland and substandard; the concepts are interesting, but not given enough room to develop, much less make me care. It feels like there are a lot of action sequences thrown for eye candy, rather than purpose, and they end up taking valuable time away from the story. The characters I once enjoyed watching, have turned into one-dimensional, well, robots. Dolores doing offers nothing but cryptic utterings; Maeve acts like a mindless Terminator; Bernard and Ashley are just following along two steps behind the plot for not apparent reason; Clem and Hanaryo return for what amounts to a glorified cameo; William... well, he's a character that has overextended his shelf life at this point.
