He smiled as she excitedly said his name. They seemed to be making some progress. Although he knew that if anyone saw him, he would be in big, big trouble for talking to their new "specimen". But Kassandra wasn't just some fish in the ocean. She was clearly intelligent and probably has her own language and culture. He could only imagine what he would do if he was in her position and trapped by some random creatures that were doing tests on him without his consent. Maybe if he talked to his higher ups, they would let her go and they could learn more about her kind in a more sensible way. 

He watched with curiosity as she did some motions that seemed to indicate that she was hungry. It was interesting that both species had the same way to indicate hunger by rubbing on their stomachs. She seemed to want to eat fish, which isn't that hard to get because they were in the ocean, but he wondered what were the implications of doing such. 

Would he get in trouble for this? They told him not to do anything but watch her. But it felt wrong to make her starve like this even if it was "in the name of science". 

Watching her repeat the motion again, made him feel guilty and he knew that she was definitely starving. He gave her a nod to show that he understood and sneaked into the cafeteria. Luckily it was late and no body seemed to be there. He grabbed a handful of fish and tuck them into a towel. Then he managed to sneak back into the observation room without anyone noticing. He thought it was too easy, but he supposed they were used to ignoring him anyway. 

He quietly opened the top and slipped a few of the fish in.
