Lost

Charlotte Staples Lewis was a gifted cultural anthropologist, who grew up on the Island where her parents were members of the DHARMA Initiative. She eventually escaped with just her mother, leaving her dad (and possibly two younger sisters) behind. She spent the rest of her life trying to find the Island again. This was mostly due to her mother's insistence that she had made it all up, and for a chance to find her father again. She then finally parachuted back onto the Island on day 91, as part of the freighter science team. After initially being held hostage in Locke's group, Sayid traded her freedom for Miles, and she arrived at the beach camp with Daniel Faraday (who she shared reciprocated feelings for), where her presence aroused the suspicions of the survivors due to her secrecy and dishonesty about their mission while on the Island, as well as her attitude to the others. Following Benjamin Linus's turning of the frozen wheel and the increasing frequency of the time flashes that ensued, Charlotte began suffering the effects of temporal displacement, and she eventually become unable to travel with the other survivors. She succumbed to the illness 16 days after her arrival on the Island, dying by Daniel's side.
