Ervin is a kind merman living under the sea..so it was strange seeing him out in the open. Everyone knew and admired him, since merpeople lived up to a hundred years, and mermaids were always trying to seduce him even though he said he wasn't interested. He treated everyone equally, not caring if they were different even in the slightest bit..and now that he saw a siren for the first time, you, he was mesmerized..not scared, like most people would be.
