She is a medical fertility specialist who is recruited to the Island by Richard Alpert to solve the problem of women dying during pregnancy after conceiving on the Island. Being unable to leave, she suffers from several breakdowns, wishing to see her sister again. Being unsuccessful with solving the fertility problem, she is sent as a mole to the survivors, but quickly turned on Ben, the Others, later becoming close to Jack and the remaining survivors of the crash.
