Cindy-Lou Kreb was an employee in the human resources department of the H&H Tools Company.
She sent out multiple e-mails to other employees regarding updates to rules and regulations from CEO Anthony House. The CEO trusted Cindy-Lou throughout his mental deterioration, asking her to monitor the emails of those he suspected of conspiracies against him, such as Henderson. In the end, even Cindy-Lou was under suspicion of the mentally fragile House brother. Her ultimate fate is unknown.
Cindy-Lou Kreb is mentioned only in Fallout: New Vegas.
