It doesn't say the incident they can't mention was 3 years ago just that Tina said 3 years ago it was hard. It's a bit below the belt that they've even mentioned it (the incident) and then said they can't mention it...it causes speculation obviously. And at the end of the day, scarlett is only 17. It could be literally anything, medical, custody agreement, a legal dispute. I'd be fuming if I was tina. I get the feeling ryan won't care either and will use it as an opportunity to push scarlett further out there
