Panel 1: We start off with Connie gushing about how lucky Elly is to have a child who can get married conventionally.
Panel 2: Not that there's anything wrong with that. He and his life partner could get married but the pageantry she and Elly both love would not occur for her.
Panel 3: Elly then explains her life philosphy that states the circle of life is complete when their children settle.
Panel 4: Connie states she has no problem with a new generation taking over the reins.
Panel 5: Elly has no problem either. All they have to do is blindly obey the will of the people who gave birth to them. That's right. The umbilical cord must never be cut. Mike, Liz and April must be tangled in apron strings forever.
Hypothesis #1: This will go over big with the weak, insecure people who want to control their children for as long as possible because their vanity gets in the way of being moral human beings who remember they too must die. Not for them the realization their children must live without them.
Hypothesis #2: It seems increasingly unlikely that Elly will be able to exert too much control over an adult April's life. Given that she will not be able to fulfill her primary mission of deciding what shape the child's life will take, she sees no point in reminding herself of that failing. This explains her coldness to her youngest child.
