Beatrice Gigawatt: I know she likes making expendable clones of herself but I am not sure if she can make them spawn inside her. I would like to suggest the idea that she uses some kind of teleportation device to teleport her own clones into her womb, stomach and bowels as a way to keep herself entertained at some lonely night. It may be implied the clones can come out alive or not, depending what you'd prefer in that case. Either way, the clones aren't pleased and they can be heard complaining and wishing their creator she would burst like a balloon.

Beatrice definitely disposes of her clones through vore most of the time. In fact when they don't explode on their own for some reason, or end up getting lost in a lab accident, she usually ends up swallowing them whole or... teleporting them into her stomach as we see here...
