"You can't stay in morph that long, and you know it."
"I know. But I have to make sure no predators come around. I have to get them food. And I have to morph at least some of the time, so they can imprint on their mother here in the wild. Look... I know it seems stupid to you and Marco and probably everyone. But I have to do this."
