Lindsey (Free To Be You and Me)

Lindsey is a woman working at a bar Sam applies at.

Background
Lindsey meets Sam when he takes a job in the bar she's working at. He introduces himself as "Keith".

She quickly develops a liking in Sam, and tries to get him to tell her about his past. Sam is reluctant, and tells her that he "made some mistakes", and "did some stuff (he's) not so proud of", adding that people got hurt.

Lindsey takes this to mean that Sam, like her, is a recovering addict.

She eventually challenges Sam to a bet of sharing life stories over dinner if she wins a game of darts. Sam agrees, just to get her off his back, and promptly wins the game quickly.

Later on, a trio of hunters enter the bar. They appear to recognize Sam, and call him by his real name. When Lindsey tries to question him about it, she is told that "Sam" is a middle name. Sam hurriedly takes the hunters away to a table, leaving Lindsey suspicious.

Two of the hunters return sometime after and take Lindsey hostage, threatening her if Sam doesn't drink their vial of demon blood. Sam refuses, and brutally dispatches the hunters, who eventually let go of Lindsey and leave.

Trivia

 * In a promo for the episode, Sam is shown having sex with Lindsey, which explains why he is not initially startled when he wakes to see a blonde woman in his bed.
 * Had this scene not been cut, Lindsey would have joined the list of Sam's lovers who did not turn up dead.
