what is down there?

Two things come to mind.

One: it's some sort of laser satellite dish thingy and the kids are suspended over the firing grid as a form of Easily Escapable Deathtrap as bait to lure some hero into fighting a Big Bad somewhere offscreen.

Two: Those eight ports around the bottom of the dish lead to the holding pen of a tentacle monster and we're about to have a heaping helping of wholesome loli tentacle rape.

Tentacles, most likely.

My first thought was sacrifices to Dagon.

It's the History Eraser Button.

the first unfortunate test subjects for the DFE (Delete Fucking Everything) Device

... Anyone else notice that the girl in front has her hands on backwards?

Clearly, this is the machine for disposing of the faulty clones.

Or they are trying to fix the problem with her arms

Look at them they do not extend as much as they do even being hanged by their arms they are still bend

Somehow it sounds elegant the way you said it.

I don't know... I would prefer if they gave them a chance to live. They are human beings after all (I think). As for the hands that are backwards, it can be fixed with surgery, I'm pretty sure.

It might sounds weird, but I don't like when people are getting hurt.
