"Your mother made a wise call there," Jack said, crossing his arms. "A siren song has far too much power to be used lightly. However, if you never use it, you will never know how to use it. There may be times you will be tempted to use your voice, and if you don't know what you're doing, the results could be... disastrous."
Jack grinned when Caleb defended his actions. "I assumed as much," he said. "Ever the Pegasus, aren't you? Very good."
Jack rubbed his hands together thoughtfully, looking Caleb over. "My song is different from yours. I can beguile with it, enchant a mortal soul, but I cannot seduce the way a siren can. My songs are dirges." Jack's dark eyes found Caleb's. "Would you let me hear yours? I am no mortal, but their... emotions are not unfamiliar to me."
