"Friday Night Bites" is the third episode of the first season of The CW television series, The Vampire Diaries and the third episode of the series overall. It was originally broadcast on Thursday, September 24, 2009. The episode was written by Barbie Kligman and Bryan M. Holdman and directed by John Dahl.

Caroline (Candice Accola) awakens after the night she spent with Damon (Ian Somerhalder) to find bite marks on her neck. She tries to escape from her room before Damon hears her, but he thwarts her attempt and attacks her again.

Bonnie (Kat Graham) worries about Elena (Nina Dobrev) being with Stefan (Paul Wesley) after the bad feeling she had when she touched his hand. She tries to talk Elena out of committing to dating him but Elena is not convinced and instead she arranges a dinner at her place where Bonnie will have the chance to know Stefan better and see that there is nothing wrong with him.

Vicki (Kayla Ewell) invites Jeremy (Steven R. McQueen) to a concert as friends. But he becomes angry, because he wants to be more than her friend and, out of frustration, he accuses her of only sleeping with him for the drugs.

Tyler (Michael Trevino) picks on Matt (Zach Roerig) for his lack of action as Elena and Stefan grow noticeably closer. When Tyler throws a football at Stefan's head in an attempt to make a fool of him, Stefan deftly catches it, surprising everyone. Elena suggests that Stefan should join the football team in order to make friends, something that Stefan does even though at the beginning he is not very positive to the idea. Stefan asks Mr Tanner (Benjamin Ayres) to let him join the team but Tanner refuses because Stefan embarrassed him during history class. But Mr Tanner lets him try out and, impressed by his skills, lets Stefan join the team.

Meanwhile, at cheer practice, Caroline shows up late because of Damon and Elena messes up the routine and eventually stops to watch Stefan play football.

Elena and Bonnie prepare the dinner while waiting for Stefan and Bonnie tells Elena that she keeps seeing the numbers 8, 14 and 22, but she does not know what they mean. Stefan arrives but the dinner is awkward until Elena mentions that Bonnie's grandmother claims that their family are witches that come from Salem. Stefan tells Bonnie that her family heritage of witches is something to be proud of and Bonnie becomes more comfortable around Stefan.

Caroline and Damon arrive unexpectedly and Stefan tries to convince Elena not to invite him in the house but she does not listen. During the evening's conversation, Damon makes a cryptic comment referring to their past with Katherine. Elena guesses that Damon also loved Katherine, surprising him by expressing her sympathy for him having lost her too. Meanwhile, Stefan confirms his suspicion that Damon is feeding off Caroline and attempts to convince him that humans are not to be used as toys. In response, Damon reminds Stefan that he has been invited into Elena's house and he can come back whenever he wants and do whatever he wants. He comes back in the evening and invades in one of Elena's dreams.
