Demeter didn't much see where his other daughter came into this. She'd showed no cruelty to Melinoe nor had she been cold to her - something which Demeter felt she had all rights to do. Melinoe simply showed less interest in Demeter than Makaria did. "My home has been open to your children since I came to this city," Demeter reminded him, "and I have taken care of both of them at times."
At the comment about Olympian wrath, Demeter only expression was of slight annoyance at being corrected, a well, fine, I suppose you've got me there.
