Erebos looked down at the one on his arm and pat her hand gently again when she offered what she did. He did not express gratitude for it, nor did he make similar offers to her. It was clear in his mind that Persephone could come to him for whatever she needed. Whenever she needed. Always.
But as he considered this, he slowed their steps. Perhaps it did need to be said. Just once. Just here. So she knew.
"I am always at your call as well," he said seriously. "Whatever you may need of me, you have." It had always been this way between them. In his world he would not have needed to say it. Now, he could be assured that he never need to say it again. It pleased him to give her this knowledge.
