Believe me, a lot of us are very troubled about it, too! And if there isn't a way to send them off this world, they certainly will not be alone. Quite a number of children have been born in this world since people started appearing here, and many of them are adults now. Plenty are part of the research division! So if we can't find a way, there will be more still looking for solutions after the majority of folks go home. And I know that those who don't have a life to return to may choose to stay behind, as well.

So assuming the world doesn't completely fall apart once we leave, it'll be just fine!

...That was meant to be reassuring. It wasn't reassuring at all, was it? Oh, bother.
