Demeter stepped towards her brother, narrowing her eyes on him. "How dare you suggest I would harm any child of Persephone's, no matter how it came about. She is my blood and my life."
Demeter hated this. She hated the ease with which these two moved around each other, there in her very own house. Hades had come walking into her home and shown, without a shadow of a doubt, that he believed Persephone belonged to him. And if Persephone agreed so readily... what could Demeter even do to protect her?
And when Hades said she feels lonely during summer there came no argument from Persephone. Her own beloved daughter was lonely in her presence. Demeter had tried, so hard, to be everything she could to Persephone, to give the girl everything she could possibly desire. But Persephone was lonely with her.
It cut Demeter more deeply than anything else her brother could have said.
The only comfort she could take was that there was on oath made on the black waters. It would bind Hades. Persephone would be safe.
"I love you," she told Persephone sadly. "I wish you every happiness that this world has to give."
She didn't look at Hades again. Holding her breath Demeter walked past them back to the door.
