Addam was a marine biologist, one of the few that got to specialize in the half human-half fish community. You had to have a shit ton of knowledge to even touch them, they simply didn't want to risk them. They were too vulnerable to human things like sickness because their immune systems didn't grow up on theirs.
Addam was moving past the tanks of the siren and mermaid pups that had been caught by themselves if they had been injured or lost.
One of them was Addam's favorite, a little siren pup, she loved him and often clung to him whenever he pulled her out of the water and into his lap. She was also playful so they were often splashing in the water together. He still remembered when she had been too scared to even show herself to him. Addam had no complaints, she was an absolute sweetheart.
He walked to her tank and Aegon (he hated him with a passion and didn't trust him, he had barely past and he never looked like he gave a fuck.) Like this job was only making him cool but Addam was disgusted.
Addam started walking over there and the little pup went to hug Aegon before the boy scoffed and pushed her back into the water, standing up and walking away.
Her tail/scales had gotten tore slightly so she was bleeding lightly. She started crying and Addam approached her.
