Susan's arrival alone might be what disarms the fight before it can even begin. Angered though he is, Childermass isn't about to throw any punches with Lauren's little brother showing up to the way he has. Someone older and it would have mattered much less, but one irritated look shot Susan's way later and he's lowering his fists back to his sides.

You don't drag a child into a fight. It's unconscionable.

"Yes," Childermass says, even if his sharp tone and the clenched set of his jaw say something totally different. He looks back over at the merman he'd previously shoved back (who looks equally as offended here) and the tense silence that's fallen between the two of them drags out for a moment before he adds, "Only a misunderstanding, I'm sure."
