The main thing I feel about this is irony. It seems ironic that the Heapsters receive the most development and become most fascinating when 99% are killed.

Now that they're dead I actually care to know more about them, unlike when they were around and could not care less - but that's mostly in part from all the development Jadis got this episode.

Hopefully we'll find out more about their origins, what that place was, the purpose for the helipad, and ultimately if Jadis does make her transformation into the next main villain.
