Keeper Mike Bates was there to give a fully recovered Karen an extra support and encouragement she needed once she was reintroduced to the orangutan habitat at the Zoo. He said, "She's better than new!" Mammal curator Karen Killmar, Karen's namesake, said, "You can see a difference in her. She's livelier and her eyes are brighter. She's getting mischievous, teasing the older females. She didn't do that before."
