Yeah... you're right. But it certainly won't end THIS drama... there's way too much involved on both sides. Lots of money, lots of anger about what's gone on over the daughter's custody and health... this particular woman who lost custody has shown that she's going to do everything in her power to make everyone miserable ... but what the heck, she was making them all miserable beforehand, what with the hiding the child from him & all.
From afar, it's hard to tell what her problem is ... what she's so angry about, or if she's one of those rare people who gets a target in her sights & can't let it go, will destroy everything (even her own children) in the attempt to destroy the target. But it's sure sad to watch sometimes.
This evidence looks like it will at least help one part of the puzzle get put together so that at least he gets SOME relief, sooner or later. Your suggestion is good I think... better if he can convince the docs not to come back against him or charge interest or anything when she FAILS to pay her portion of the bills.
