Abducted: September 5, 2001 -- Seattle, Washington
Returned: August 14, 2004 -- Highland Beach, Washington
Known Abilities: Alternate reality creation

A widow since her husband and son were killed in a car accident, Alana Mareva (Karina Lombard) returned with the ability to create alternate realities out of people's memories. Alana's ability enabled her to form a bond with Tom Baldwin, a relationship forged by the future so that she could help him through the difficult times that lie ahead.

That relationship was tested, however, when she betrayed Tom by alerting fellow 4400 Gary Navarro that NTAC was after him. This forced Tom into a precarious position, and he eventually attempted a trade to win her freedom. But Tom couldn't go through with it, which meant Alana had to go on the run in order to avoid arrest.

After working out an arrangement with NTAC, Alana returned to Seattle. She used her ability on Jordan Collier, enabling him to recover his memory. This allowed him to testify on Kyle Baldwin's behalf, thereby securing his release from prison. Tom's family was not reunited for long, however. Alana was re-abducted by the future, disappearing in a ball of light similar to the one that'd taken the original 4400.
