He wished Persephone was here. She was good at distracting mortals and she'd set him on his way with no questions. His inherent sense of justice wanted to tell the boy he'd just survived a Siren encounter and to be grateful Hades was there, but that would sound insane.
He also had no idea how to offer comfort to a complete stranger. "She had errands to run. I apologize for interrupting but she is family and I wished to say hello." Not a complete lie. Ligea was related to him, even distantly.
