The friendship between Fiona Coyne and Holly J. Sinclair is known as Folly J. (Fiona/Holly J.). Though they strongly disliked each other in the begining, they eventually became best friends in Season 10.
Upon transferring to Degrassi with her twin brother Declan in Season 9, the last thing Fiona has on her mind is getting to know her peers. Having lived in so many different countries throughout her childhood, she has trouble making friends, and comes across as distant and anti-social, preferring either her own company, or her brother's.
Fiona does not approve of Declan's growing interest in Holly J., referring to her as the "dragon lady of Degrassi." Worried that she is losing her only friend to Holly J., Fiona does her best to drive a wedge between the two throughout their relationship.In Keep On Loving You, Declan gives Holly J. his grandmother's antique bracelet. He and Holly J. have sex for the first time, and she tells Declan she loves him. When Declan doesn't say anything in response, Holly J. confronts him at school the next day, and asks whether he actually loves her. Declan hesitates, and then says that his feelings are "not that simple." Heartbroken, Holly J. leaves him in the hallway.
She finds Fiona by herself in the library, and gives her the bracelet. Fiona is shocked, and tells her that Declan must really love her to have given her the bracelet. When Holly J. asks her why Declan couldn't tell her he loved her, Fiona tells her that the only girl Declan said he loved ended up cheating on him, leaving him devastated. A relieved Holly J. goes to find Declan, and the two reconcile.Meanwhile, the Coynes are planning to move back to New York. While Declan is sad to leave Holly J. behind, Fiona is eager to see the two end their relationship. Unbeknownst to Holly J., Declan hacks her e-mail account and applies for a Manhattan internship at TVM Studios on her behalf. Holly J. gets the internship, giving herself an excuse to spend the summer in New York. Mr. and Mrs. Coyne agree to let Holly J. spend the summer with the family, a prospect Fiona does not look forward to.
After the twins arrive in New York with Holly J. and Jane (whom Holly J. and Declan invited after her break-up with Spinner) in Degrassi Takes Manhattan, Fiona insists on isolating herself from the other three, choosing to stay in the family's penthouse. Jealous of how much time Declan and Holly J. are spending togther, Fiona asks Declan if he and Holly J. are going to "couple out" for the duration of the summer. Declan tells her that that was the reason Holly J. was invited to stay with them, and assures his sister that she will find something to keep herself busy.
The next day, Holly J. arrives at TVM Studios. She is shocked to see Fiona walk in moments later, and be offered an internship as well. Fiona condescendingly tells Holly J. that the "Coyne name opens a lot of doors," and that she was simply looking for something with which to keep herself busy.Fiona manages to sabotage Holly J. and Declan's plans that night by lying to the girls' boss about being best friends with Jane, who has become the frontwoman of a band TVM is interviewing. She suggests that Holly J. do research on the band, knowing that the amount of work will keep her from leaving the studio for her date to the opera with Declan. When Declan comes to the studio to pick Holly J. up, she sadly tells him that she has too much work to go out with him. Declan gives the extra ticket to Fiona.
The next morning, Fiona aggravates Holly J. by telling her what a great time she had with Declan. She warns Holly J. that no matter how close she and Declan get, she will always come first in his life, as "boyfriends are temporary," but "brothers are forever." Holly J. leads her down the hallway, presumably to her interview with Jane's band. Holly J. ends up locking Fiona in a copy room. Upon arriving on the set of the interview, she tells her boss Kristin that she's been looking for Fiona, and can't find her. Holly J. does the interview in Fiona's place.
Fiona manages to get out of the copy room, and arrives on the set of the interview after it's over. Kristin angrily fires Fiona. Devastated, Fiona phones Declan, asking him to take her home. When Declan comes, he lashes out at Holly J. for locking Fiona up, and leaves with his sister.
Later, Declan meets Holly J. and Fiona downtown, and insists that the two of them try to get along for the remainder of the summer. Holly J. apologizes for what she did to Fiona, and Fiona agrees to start fresh. Fiona then suggests to throw a party to allow Holly J. to meet some of their socialite acquaintances.
At the party, an intoxicated Fiona introduces Holly J. to some of Declan's ex-girlfriends. The girls tell Holly J. that it was Fiona who drove them all away, as if to keep him "all to herself." Holly J. tells Declan that Fiona's jealousy has her worried about the fate of their relationship. Declan then kisses Holly J. to prove his loyalty to her. Fiona sees them, and pulls Declan away. Holly J. tells Fiona that her jealousy is "inappropriate," and Fiona responds by kissing Declan on the lips. Realizing what she has done, Fiona fakes a fainting spell to avoid having to explain herself. Shocked, Holly J. leaves the party, telling Declan that she is done with coming second to his sister. Meanwhile, Fiona looks on contentedly.
The next morning, Declan confronts Fiona about her antics, and tells her that he's phoned their mother, and that Fiona will stay with her in the Hamptons until school starts. Fiona argues that Declan is all she has, and hysterically throws her belongings on the floor, calling him inconsiderate, and telling him she hates him.
Season 10The summer draws to a close, and the Coynes decide to throw a farewell party for Holly J. While Declan and Holly J. nervously await Fiona's arrival, Declan jokingly tells her that she and Fiona will be friends in no time, which makes Holly J. laugh. Fiona later makes her entrance happily on the arm of Bobby Beckonridge, who she refers to as her boyfriend.
As Holly J. leaves for Toronto, Fiona tells her that she will miss her, how much she's grown to admire her, and that she believes that the two of them could be really good friends. Holly J. is amazed at the change in Fiona. Fiona attributes her happiness to her new boyfriend, and to a good therapist. She and Holly J. hug, and Fiona waves goodbye as Holly J. heads home.
Fiona's relationship with Bobby intensifies, but his behavior towards her becomes abusive. Fiona is reluctant to talk to her family about Bobby's abuse, as she is worried that no one will believe her, given her over-dramatic behavior in the past. She drunkenly video chats with Holly J. online, hinting at the possibility of there being something wrong, but does not elaborate. The two are interrupted by Anya, who has come to help Holly J. with her school presidential campaign.Declan finds out about Bobby's abuse via a photo Fiona took of a black eye he gave her, which she posted on Twitter. Declan confronts Bobby, who denies hitting her, and tells Declan that Fiona is crazy. When Fiona arrives, Declan notices that her black eye is barely visible. Fiona admits that she "enhanced" it with some eyeshadow, which causes Declan to lose his temper, as he thinks that Fiona is lying about Bobby to get attention. He later calls Holly J. to complain about his sister. Holly J. advises him to listen to Fiona, as she suspected something was wrong when she was chatting online with her. Declan talks to Fiona, who insists that she is not lying about Bobby's abuse. After she shows him bruises she received when Bobby threw her down the school's stairs, Declan is convinced. He mentions that Holly J. was concerned about her. Fiona says she misses Holly J., and after Declan leaves, she orders a plane ticket to Toronto.
Holly J. is surprised to see Fiona show up at Degrassi later that day, and the girls go to The Dot to talk. Holly J. inquires about why Fiona is back, but Fiona says that she just missed the city and Degrassi, and wanted to visit. When Mrs. Coyne finally tracks her daughter down, Fiona admits why she really came to Toronto. Mrs. Coyne assures Fiona that she is going to press charges against Bobby, despite Fiona's plea not to.
Mrs. Coyne is making plans to have Fiona transfer to a school in Vermont, but Fiona begs her to let her attend Degrassi, as she knows the students, and enjoys spending time with Holly J. Mrs. Coyne reluctantly agrees, as long as Fiona works hard, and has someone to keep an eye on her.When Fiona comes back to Degrassi, she tells Holly J. that she's getting a condo in the city, and begins shopping online for home accessories. Holly J., whose family has been having money problems, is jealous that Fiona can spend her money so frivolously, while she does not have enough money to put towards her SAT prep course. Before Fiona makes her purchases, she creates a new password for her account, and lets Holly J. see it, claiming that as friends, they can trust each other. Holly J. later goes on Fiona's account, and takes $2000 for her course, promising herself to pay it back.
The next day, the girls go to The Dot for lunch. While on her laptop at lunch, Fiona notices that $2000 was taken from her account. When she asks Holly J. how much her course was, Holly J. admits that she took the money. Fiona is hurt, and tells Holly J. that she would have given her the money if she had asked her for it.
The two meet at Fiona's locker the following day, and Holly J. apologizes for taking Fiona's money. She realizes that because they're both without many friends, they need to be able to trust each other. Fiona says that she will forgive Holly J. as long as they remain friends, and that Holly J. gives her 200 hours of her time in the form of sleepovers and help with her classes. Holly J. agrees, and the pair walk down the hallway together holding hands, feeling good about the year that lies ahead.
