Turtles seemed okay to Roy - he was pretty sure that Mia was right and that some turtles had lived to be over a hundred years old. That would be all right - that would mean the turtle wouldn't die on Lian, and that would be nice.
Roy hadn't had any pets growing up. He had vague memories of a cat that had hung around his house when he was living with Roy Harper Sr. but he wasn't sure if the cat was theirs or just a stray that had been hanging around. But he was pretty sure that pet death would be traumatic and he wanted to spare Lian that.
