Jon has given an interview during the pandemic about what he is up to, and it turns out he's an essential worker, doing IT for a hospital.

As for their ongoing custody battle, he says the judge has now left it up to the children where they want to live, given their ages. Their next court date (like court dates for most of the country with pending court cases) has been set very far out.
