She has never actually been shown on the show, and therefore served as a running gag (as the unseen character is a popular literature device). On The Click on the-n.com (which is now redirected to teennick.com), there is a Degrassi Mini titled "Be Aware of Heather Sinclair" in which Heather is still never seen, but we are shown the other characters' reactions to her mean comments instead. It is implied that she graduated in 2006 according to the occurring events in her Degrassi Mini.
Heather is first mentioned by Terri MacGregor in the season one episode Parents' Day. She mentions to Ashley Kerwin that even Heather says Ashley's morning announcements are better than the N.A.K. hosts. Terri says that she has an agent, to which Paige Michalchuk is disgusted because of her apparent overbite.
In Cabaret, Paige tells Terri that her duo with Ashley sounds lamer than Heather's Highland Sword dance.
In When Doves Cry (1), Craig Manning is giving a speech in Mrs. Kwan's class. When he finishes, Mrs. Kwan calls up Heather. Heather is seen walking behind Craig, only showing part of her legs, which were covered by her pants.
In Mercy Street, Paige calls Heather's eyebrows "tragically over-plucked", and Emma says her tweezers should be confiscated.She would be mentioned in passing throughout the next seasons, and she would almost be shown in the season four episode Neutron Dance during a yoga class, but her arms cover her face.
In Islands in the Stream, she is partners with Emma for the tryouts for Degrassi's official Trivia Team. She is ranked at #2 on Rick Murray's list of hot twenty girls in the entire school.
It is mentioned in Time Stands Still (1) that she had contracted mono before the Whack the Brain Contest, allowing Jimmy to take her spot. This would eventually lead to him being shot and paralyzed by Rick Murray.
She is mentioned in West End Girls when Ashley says to Craig they need to get to the food before Heather Sinclair does.
In Foolin', Toby Isaacs tells J.T. Yorke that Heather auditioned for the video announcements with a booger dangling from her nose hair. When J.T. fails his audition for the video announcements because he is too preoccupied over the fact that Liberty is pregnant, Liberty says that Heather Sinclair gets the job.
In The Lexicon of Love (2), Paige tells Marco that she has had feelings for another girl, and Marco guesses that the girl is Heather Sinclair, as he has seen the way she looks at Paige. She responds to the thought with an "ew".
In Our Lips Are Sealed (2), Paige and Alex laugh over the fact that she is wearing volley shorts to school.
In Can't Hardly Wait, Ashley puts her hands over Jimmy's face and tells him to guess who. He guesses Heather Sinclair, and she tells him that he is funny.
In the Degrassi Mini, "Be Aware of Heather Sinclair", she terrorizes the students of Degrassi and states that Peter Stone is hot and evil. At the end of the clip, Mr. Simpson calls her down to the Main Office because she parked her car in the handicap parking space again. She is still unseen for most of this short (as the camera is from her point of view), though we get an incredibly short glimpse of her face when she closes her locker door.In the Degrassi Mini, "Toby Dynamite", Heather is running for student council president against Liberty Van Zandt. She says "If you vote for me, I'll make sure there are no more pesties in the food! I'll make sure all the school dances include a free-" she is still talking, but is cut off by Snake talking to Toby and Liberty. The last thing she says is "Vote for Heather!" Then, for her "skit", she plays the trumpet.
In season seven, Holly J., Heather's younger sister, transferred to Degrassi Community School with the other Lakehurst students. Holly J. proved that she followed in her footsteps; she was pretty, popular, and mean.
On another Degrassi Mini, "Queen Bees", Holly J. and Paige Michalchuk then have a face off for who is a better queen bee. When told that Holly J. is Heather's younger sister, Paige responds "She's the devil's spawn!"
When her family was having financial problems in Money for Nothing, Heather sent Holly J. a check so that she could go to the Cheer Leading Regionals. She told her mother that no sister of hers would miss the Regionals.
Seasons 10-11U Don’t Know (1), Holly J. admits that Fiona is more a sister to her than Heather ever was. While Holly J. is looking for pictures of herself as a child, she comes across old pictures of Heather, Heather's pet turtle, and their family, but none of herself. It is revealed that Heather had a nose job to fix the "Sinclair schnauze" she inherited. Heather does not have a compatible blood type with Holly J., so she is unable to donate a kidney to her. Their mother later tells Holly J. that Heather was a complicated birth, which made it so she was no longer able to carry children.
