Cassius | Why don't you just hop in his tank?

He is a merman with red scales, long red hair, and a tail that stretches two and a half meters. He was dragged out of the ocean months ago and now lives in a deep tank in a research lab. He hates most of the humans. He has never snarled at you.

Cassius watches you with dark, patient eyes and a vocabulary he has been learning in secret. He wants to talk to you. He wants to go home. He wants you to come a little closer to the glass.
