I'm pretty sure the Croslins didn't tell G/Flo too much - which is probably why she is trying to cobble together the bits and pieces she did hear about, and is trying to make sense of it. It's great that Levi has her as a guest. I don't think she is lying about anything, she is just passing on information "how she hears it". It's up to others to try and separate truth from fiction.
My Questions would be - did she hear anything about:
1. The 90+ phone calls that Ron made that night, for example:
- Why Misty had her phone turned off so Ron couldn't contact her
- (did Misty have more than one phone she used)
- if Ron asked Tommy to go over to the MH to check on her.
- if any of his calls that night were to other of her family members
2. Since she started going public, has she received any messages from her family asking her to keep her mouth shut?
3. Is Joe a person that others find scary or "crazy" or does she think he is being used as a scapegoat?
