David Brent's fourth date in The Office Christmas specials is Carol. Brent tells Neil that he has a date for the Christmas party, even though his first three attempts to find a suitable companion go badly.
With Gareth's help, Brent searches internet dating sites and arranges three unsuccessful dates. Their failures underline Brent's desperation to appear popular and successful after being made redundant from Wernham Hogg. He is determined to impress Neil and the documentary crew by arriving with a glamorous partner.
Carol's arrival changes the mood immediately. Unlike the earlier women, she and Brent get along, and she shows genuine interest in him. She later gestures through the car window for Brent to call her, giving him one of the rare moments in the series where his confidence appears to be rewarded.
The character is sometimes confused with Anne, who is Tim's new desk-mate, or with one of Brent's earlier dates. Carol is specifically the fourth date and accompanies him to the Christmas party in the second special.
