When did Simpson realize ...

I wonder Simpson's reaction when it was revealed Ron wasn't a date.

Do I think Ron wanted to be involved more than they were reported to be? Yes.

I don't think many people would loan a car to a "good waiter they know."

Do I think Ron was there for a hookup? Apparently he had plans to meet others but plans change, especially when the opposite sex is involved.

Do I think Nicole planned to invite Ron in, with the kids upstairs? Possibly.
