I don't like those options individually.

>5: 1,3, then 4 in that order. Tell him that once Emily is stronger she'll have ways of sending him to a better place, then let Mephita chime in. Let him know that together you all can make Lomam better, and that it doesn't have to be a horrible place.

2 is just stupid.

I second this. It sounds like the idea with the highest chance of success. Let Meph tell him how trustworthy the kids have been, they haven't tried to screw her over and let her live with and help them. As long as he's willing to work with the kids, he can stay and help out until they're ready to send their allies home.
