Life with Lilith is fascinating; it's easy to see why the old spoil children. Really, you're way pas the palm glow and you just hope things are good for them. That's a pretty deep well of guilt to draw from.
I think the grandparent creature is lost to good intentioned desires, hopeful to see their grand children live idyllic lives. Ego and legacy do play a part and at what costs, almost always at odd with ones own children, truly fascinating.
