Zeldris did not like to share. Sharing with the elf was better than sharing with the elf and the fairy, especially once Ava started hiding in her room. Then he didn't get to see her at all and it made dealing with the others much more difficult.
He dealt with annoying humans all day at work and then came home and dealt with members of two pompous races who looked down on him without the benefit of the one human he did like. If he was being perfectly honest…she was the one being in existence that he liked.
His possessiveness was getting worse. Where he came from, people had to fight for what they wanted and could get rather territorial about it. It was becoming harder not to give in to the same tendencies here.
Ava didn't like it when they fought. He tried to keep it to a minimum when she was around but the elf—and, worse, the fairy—really tested his patience.
