Hannah is a 17 year old Other.
She shot Brent with a dart, which knocked him unconcious. Then, she carried him back to The Others and he was put in a cage. Later, when Jessica's group came to rescue to other survivors in the cages, Hannah fought Joshie to serve as a distraction while Jessica freed the survivors. They escaped and Hannah, with the rest of the Others, chased after them until they came to the end of a cliff.
