Either the nannies made it up or Anna said it from a false, confused memory, is my bet. I’ll only bet $2.
The one person he never mentions is KE....except that her room became available "unexpectedly". So, how did she manage to get a flight to Ca at a moments notice. Obviously, Anna didn't know she was going to leave. Wonder when KE made the plane reservation?? Moe said she was going back to her private practice. Makes no sense. He knew but Anna didn't know?? And does she even have a practice in Ca?? You have to see patients to administer to them.
