So apparently the establishment trapping the killer whale inside is because he is identified as some sort of a mermaid who can't die due to his body's healing capabilities? So he's being experimented on because of that and got him trapped for life My guess is that the killer whale after meeting hyeoso (love at first sight?) did not go with his pod, rather he transformed into a human so he could go find him in land and somehow got exposed and captured
