I suspect Ethan isn't working, and that's why he wants to remain off-camera. Chauncey was buying him food on Tuesday afternoons.
I do wonder how it's affordable for Herb and Gina. Chauncey probably makes a better living now that he's mass-directing crowd funded movies every few months, but health care & California living costs have to pile up. They spend like $100 every 2 months on paper plates for example.
Also, it's funny how Ethan looks EXACTLY like Gina, and Chauncey looks EXACTLY like Herb. Although Ethan has more common interests with his father (both into pop culture art), and Chauncey seems closer to Gina (they work out together at the gym / shop at CostCo together). I think this is due to being around each other so much (not throwing shade).
