Ocean boy

Charlie suddenly realised he would have to defend the new boy. “Leave him alone,” he said.
“Who asked you, Charlie Bone?” snarled the beefy third former.“
"I’m responsible for him,” Charlie said in reasonable tone. “His name is Dagbert Endless.”
“I suppose he’s one of your peculiar ‘endowed’ people,” Rupe piped up with giggle.
“They’re not peculiar,” Fidelio said evenly.
“Ok. So what do you do, new boy?” Bragger climbed on to rail at the foot of Dagbert’s bed. “Forgive me for saying so, but Endless isn’t a name.”
All at once Dagbert straghtened up. He fixed Brager with his aquamarine eyes and said, “My name is as endless as the ocean, and I drown people.”
