Jack Harcourt Deveraux and Jennifer Rose Horton are fictional characters and a supercouple from the NBC daytime drama Days of Our Lives,[1][2] whose history spans from 1989 until 2012.

For their portrayal of Jack and Jennifer's romance, Ashford and Reeves won Soap Opera Digest Awards for Favorite Supercouple in 1991 and Best Love Story in 1992.

Desperate to please his father (who was a sociopathic misogynist), Jack tried to be Harper's son and he worked hard at bringing down the people who had scorned him: Kayla and Steve.

Desperate to keep "The Spectator" from printing an exposé on his dirty dealings as a politician, Jack purchased a controlling share and changed his destiny.

Her initial feelings towards Jack were unfavorable due to his treatment of Kayla and Melissa, but Jennifer soon learned that her boss had a different side to him.

Jennifer refused to let Jack make excuses for the terrible things he had done, and she called him on the carpet whenever he tried to use his newspaper to gratuitously hurt people he didn't care for.

Jack was adorably endearing helping feed and care for the very young child, and seeing him with the baby made Jennifer develop warmer feelings towards him.

Jennifer was furious with Jack for failing to warn her about this when he had known it was happening, but in the end, she turned to him for comfort when she realized he just didn't know how to tell her.

At this time, Isabella's blind acceptance of him, as well as the other good influences in his life, had pushed Jack into becoming the kind of person who took responsibilities for the things he had done.

Frantic to protect Isabella from this harsh and terrible truth, he ripped out the truth-revealing pages and gave her the rest of the diary.

Furious that a "little girl" presumed to tell him what to do, Harper told a frightened Jack that he would kill Jennifer if she continued this behavior.

Although Harper was in jail, Jack knew that his adoptive father would find a way to make it happen, so he pushed Jennifer away by firing her.

When Jennifer was set to marry Emilio, Jack kidnapped her on her wedding day so that she would have time to think about her future, and he confessed his true feelings.

It brought back all of his fears and self-loathing and despite counsel from Steve and Jennifer's persistent love, he pushed her away yet again, this time making her feel so hopeless that she embarked to New York on an adventure to try to protect her boarding-school best friend Katarina from an arranged marriage to Lawrence Alamain.

Jack rushed back to Salem when he found out Steve had been hurt and he spent hours at the hospital with Kayla and his mother and sister.

The kiss triggered a flashback of what happened with Lawrence, but a heartbroken Jack thought that Jennifer had finally come to her senses and begun to see that he really was a dangerous man.

Jennifer pressed charges against Lawrence and Jack stood by her side, gaining new insight as to how he had made Kayla feel during their own trial for his rape of her.

Jack, who had lost his paper and his fortune, became obsessed with the idea of making his money back and began to get himself involved in get-rich-quick schemes, many of which Jennifer found impractical and shady.

To make matters worse, these business ventures would often cause Jack to disappear, sometimes for weeks at a time, without so much as a phonecall to Jennifer.

Eventually, after tempers calmed and they were able to discuss the problems rationally, they agreed to return to Salem where they would attempt to work out a custody agreement of Abby.

In his latest attempt to win Jennifer back, he suggested the three of them all move in together under one roof, as neither of them had a place to stay, and the stability would be good for Abigail.

However, when Jennifer began to date the sensitive and romantic Brandon Walker, Jack was determined to continue, especially after he interpreted it as working.

As his heart belonged to only Jennifer, Jack tried to let her down gently, but when Greta (who had recently been dumped twice for other women) realized she was being rebuffed again, she began crying.

When Jack, guilty at this all this happening as a result of his deceptions, stops the interlude just short of sex, Jennifer finds herself surprisingly disappointed and very confused as to how she feels.

In October 2003, Jack began working with police officer Abe Carver, leading to both men supposedly being murdered by the Salem Stalker (Marlena Evans).

In May 2004, it was revealed that Jack and all of Marlena's victims were alive and being held on a tropical island by Tony Dimera, who had faked all of the murders.

During this time, despite possible temptations on either side by Patrick Lockhart (a good-looking conman working for Tony who had man who had Jennifer in his sights) and Cassie for Jack, both managed to be one of the only couples (of many) dealing with fake dead spouses who stayed true to each other.

Jennifer's opinions were mixed because although she was elated to find out the man she loved was alive, she was as angry at him as she'd ever been for letting her think he was dead when he wasn't.

Daniel was preparing to ask Jennifer to move in with him, when an eavesdropping Jack literally fell into the cake beside them, once again reuniting the supercouple.

After realizing Jack didn't purposely leave her, Jennifer is torn between the two men who adore her: 1) the father of her children with whom she has a long history (but who is unreliable) and 2) the other who she's only known a few months but has so far done no wrong.
