I can imagine them discussing the finances (that could be comingled by that time) and I can imagine if the push was too huge, Nancy grabbing her cellphone to call Savannah or Camron, to talk to them about it, and her SIL grabbing it from her hand and her accidentally falling.
The rest, however, seems too planned.
Well, if Savannah's finances were in any way the topic, it only illustrates how right SG was in keeping her in-law as far from her life as possible!
I imagine a different situation. Could a provincial and not too savvy BIL, knowing that his SIL rubbed shoulders with "the famous and the mighty", harbor the hope that SG could promote his music to the top of the charts? Something irrational. Just my idea.
