Rachel Gibson (Alias)

Introduced at the start of the fifth season of Alias, Rachel Gibson's life parallels

After being captured by Bristow's team on behalf of

Although a novice when it came to field operations, Gibson learned quickly with some help from her colleague

The episode "Solo" strongly suggested Gibson, though she is no stranger to death, had herself never used deadly force up to that point (and continued to avoid doing so). She did, however, later confess to having enjoyed beating Dean senseless with a shovel before his arrest. In the final episode of the series, Gibson shoots a man to death but it is not indicated if this is her first kill.

During the second half of the season (and subsequent to the announcement the fifth season would be the final one), Gibson's character faded into the background somewhat, appearing only briefly in most episodes. Following the birth of Sydney's child, she was no longer living with Sydney (a fact confirmed when Sydney later invites her half-sister Nadia to live with her and Grace later visits Rachel at her apartment), though the series does not indicate when or why she moved out.

In the closing episodes of the series, Gibson found herself attracted to Grace even as she carried out an "off-book" investigation of the agent's activities. She discovered he was investigating the circumstances of his wife's death and she helped him track down her killer, whom Grace assassinated with a car bomb.
