I agree, I was thinking, her being called before the grand jury might have prompted her to call a family powwow before and after. Other siblings at the table, to discuss what she should say or had said.Idk if the meeting was a “hosted” event, as in pre planned or if everyone converged on FW for advice.
I also think the 4 wouldn’t mind RWs presence.
I also feel IF RW/RAW had any clue what was going on, they would want their mom OUT of the equation & very peed off that she was involved by virtue of the 4. Totally agree with your “maternal instinct” suggestion. We see this with nearly every crime. The parent/s of the suspect rarely believe the evidence against their child true. Some, even presented with facts, will spend every dollar they have, in effort to clear their child, they simply can’t accept the truth.
Eta: if RW is an informant, I don’t find it unusual she’s in court. Someone can turn someone in or testify against them but still love them. IF either RW/RAW turned “mole”, I think it likely their decision was made as they saw their mom becoming more intertwined. And, I have no reason to believe RW/RAW are anything other than law abiding.
ETA: they knew LE was closing in after the GJ convened. I think that’s what prompted revenge discussions. Can’t we all picture G4 “I ain’t going to jail, they ain’t arresting me, I’ll shoot........”
I wonder what she was lying about to LE: the custody document, an alibi...?
