Editing Jay Cartwright (section)

=== Family===
'''Terry Cartwright (Father):'''

Jay and his dad has a complicated relationship, due to Terry's constantly insults, contradicts and undermines his son; especially in front of his friends. Terry proclaims any of Jay's attempts to stand up for himself as womanly fits and ignores them. Terry either doesn't know or doesn't care how damaging he is for his son, he seems merciless when it comes to insulting Jay. Terry's behaviour is perhaps the reason why Jay acts the way he does. Jay, although despite his dad's complicated behaviour, seems desperate to earn some form of approval from his dad.

'''Mrs Cartwright (Mother):''' Having walked in on Jay masturbating on more than one occasion, she is not fazed by Jay's behaviour. Also, she is shown to stick up for him against his dad's bullying.

'''Benji the Dog:''' It is revealed in "Home Alone" that Jay has a dog named Benji. Jay appears to find Benji's presence frustrating at times, as Benji often interrupts him while masturbating. However, it is revealed that Jay has deep feelings for Benji by being extremely upset when he was put down, and demanding he could be the dog while playing Monopoly as it reminded him of his beloved pet.

'''Jay's Sister:''' Jay's younger sister made a brief appearance at the beginning of ''The Inbetweeners Movie.''

'''Uncle Bryan''': Bryan is Jay's uncle who lives in Australia. He appears in ''The Inbetweeners 2,'' where Jay spends a year living with him. Bryan's personality is similar to Jay's dad's, and is revealed when he mocks Jay's tiny penis and reveals to Neil that all the things that Jay has texted to him was a complete lie. However, Bryan has been shown to stick up for Jay when he told Terry he presumed that he taught Jay how to fight like a girl which causes Terry and Bryan to brawl it out.

'''Michelle''' (Cousin): Neil mentions that he fingered Jay's cousin; Michelle.
