“Listen to me, don’t talk,” Jonathan Caouette tells his mother, Renée. “You need to get off the Risperdal. You need to be back on Lithium.” It’s 2010, at the start of Walk Away Renée: he’s home in New York, she’s in Houston, at the group home where he hoped she might find a mix of independence and close-to-round-the-clock care. But the more Jonathan listens to her, the more he realizes she can’t be there, that their living arrangements will need to shift—again. And in this realization, the new film picks up where the old one left off. The son must sort out what to do with his mother.
