I think we have a problem with the relative passivity of our protagonists because we're two steps ahead of them and we're irritated that they haven't caught on by now.

When the cyberneticist tried to explain to Jo exactly what Piper is and Jo just wasn't getting it, I think we were as frustrated as that woman (who was risking her life even talking to Jo!).

I think I said "robot" as one of the possibilities after the first episode. Somebody in that group should have guessed robot too. Made them look dumb.

Oh, and:

P.S. Those robot guards dogs were stuuuuuupid.
