Sharleen was an alias used by Sydney Bristow. In an effort to win the attention of criminal Martin Bishop, APO set up a situation where Sydney appeared to be in a car crash and Bishop saved her just before the car exploded. He invited her back to his house to freshen up, and whilst he was not there she hacked into his server and found the location of the Valta computer which he had stolen and planned to sell to the German terrorist organization Baden-Liga. He discovered she was not "Sharleen" when the raid of the Valta's location took place (with the Valta being destroyed but the CIA team captured). Sydney managed to escape after he kidnapped her. Bishop was then shot by Nadia Santos (The Awful Truth).
