I didn't see that coming with Saunders either, I had expected one of them to be a doll, but I thought it would be Topher, because he always says it's "his" chair, so I thought they would have a Topher for each dollhouse... but I was totally wrong obviously
or maybe they are all dolls and we just don't know it yet, after all it must be quite difficult to find loyal employees for this kind of work
I didn't like the first few episodes too much, but by now I think it's a pretty good show, I hope they pick it up for another season, but judging from the ratings I somehow doubt it
