Just guessing but I think the meeting was arranged because she was demanding more $$$$$.
Most things usually boil down to that..
She is definitely in the driver's seat.
Sounds more than reasonable. The interesting part now will be how she's going to get the agreed-upon money. With everyone watching--including the IRS, one would hope--and the Texas lawyer conduit shut down, she's going to be missing her $15K/month real soon. She doesn't strike me as the savings passbook type, so she's got to be thinking about the fast-approaching expiration date on her lifestyle.
Mr. and Mrs. Andrew Young need to be paid, too. How's that going to work? I doubt the couple planned on signing on to 18 years of child support without most generous compensation. So the couple and Rielle are probably right now eyeing each other like final tribe members in Survivor.
