Athena was in there in an instant, forcing her way between her niece and her brother, creating some distance. She felt in the same moment a spear of admiration for Marcie's fire, and a stab of frustration at her timing. If Apollo lost his temper now, there was no telling what mischief he'd wreak – or whether this fragile truce would survive it.
"Stop." She spoke the word with hard steel in her voice, warning flashing in her eyes. "Marcella, I understand this must be confusing, but Apollo is here to heal you, and that is what he's done. Once he leaves this room, he will not touch you again." She addressed Marcie, but her gaze never left Apollo. Say the words, you arrogant fool. Say it, and walk away. For everyone's sake.
