It's Ohanna's intention that Kriije accomanies Miiri, Kaara, Deeela, and Odoona back to Earth, and that Miiri makes some arrangement about kriije's future occupation. Ohanna intends to retain ownership of Kriije (albeit knowing that on Earth such a claim has no legal foundation) to prevent Kriije falling into the hands of another person who might exploit her talent for doing bad things.

That said, we've not got to the end of this particular story arc yet. A lot could happen betweeen now and then, and what's planned might not be what happens.
