Why hire an Active?
Why not hire, say, an actual midwife? Or an escort? Or a hostage negotiator?
Why spend what is implied to be a LOT more money to hire an Active through the Dollhouse?
I understand, actually, when you're doing something illegal, because no memory would be left of the crime committed (I haven't actually watched a ton of last night's episode, yet, so I dunno what the rationale behind hiring Echo-as-safe-cracker was). Or have, like, a rape fantasy you want to carry out so you give certain instructions for an imprint, rape the Active,
... apparently, I'm a horrible human being with a very dark imagination.
