I just find it's strange (and sad) to feel you have to lie so much to people close to you about thigns that the other people (if not you) take seriously.
Ummm - who lied?
Jo didn't baptise her kids to get them in - they got in via the interview.
She didn't lie to her daughters' MIL, and they accept she is what she is and they are what they are.
We all guilty of white lies on occasion - telling someone dressed up that they look great when they really look like mutton dressed as lamb etc. Turning a blind eye on occasion is what makes society go around in peaceful turns.
