If Chris cannot go back to 14BC because Barb continues to defy him by persisting in this world, or because the house will be sold as soon as she dies, then the court must find a place to put Chris. That's the law in Virginia, as written by Chris's old lawyer Rob Bell.
They tried with Gateway, maybe at the recommendation of Allyson K. Tysinger, but Gateway probably said no. Chris doesn't fit the requirements on their website. So now maybe Tysinger has some worse group homes to recommend for Chris, but even there space is limited and they might be saying no as well.
