From an article published on Sept 17 NS said this about the Moab incident:
"Addressing reports of the incident on Wednesday, Gabby's mother, Nichole Schmidt told DailyMail.com: 'It's irrelevant.
'Two people traveling together with each other 24 hours a day, it's not going to be perfect, it was an argument, and that's all I'm going to say about it.'

Taken at face value, it doesn't sound like there was great concern about the Moab incident at that time. Doesn't quite match with wanting GP on the next plane out. So it's all a bit murky to me.
