The third season of Masters of Sex has a disclaimer that ends by telling us
... the children Tessa, Henry, Johnny, and Jenny are fictional.
Thing is, Masters has 3 children in this season. I don't know the name or gender of the third, but there have been several scenes in which it is clearly stated there are 3. I don't think Jenny's name appears anywhere other than this disclaimer, but Johnny is getting a fair bit of screen time. And Johnson also has 3 children this season. Just before the baby is born, her husband tells someone "Lisa if it's a girl, and Scott for a boy" - these being the real names of her real children as opposed to these fictional ones.
But why would the disclaimer only mention 4 of the 6 children they are portraying? You could argue it's because the children are doing actual things (joining the army, working at the clinic, getting bullied, not being good at football) but Jenny isn't doing anything at all and is in the disclaimer, and Lisa is at least getting screen time but isn't in the disclaimer.
So what's going on?
