The Conners Season 4 Ending Explained

Thus it is Harris Conner-Healy (Emma Kenney) who ends up experiencing real heartbreak when she rejects her fiancé, Aldo (Tony Cavalero). The young couple's entire relationship has been built on impulse, so perhaps it's not too shocking that they end up on opposite sides of the page while trying to plan their wedding. In Aldo's case, he wants to start a family immediately, while Harris wants to enjoy their relationship for a little while longer — or at the very least nail down a regular job before having a baby. The large difference in their ages and the fact that Arlo has an established job as a tattoo artist while Harris is currently unemployed also factor in. 

And the couple don't simply delay their relationship — they break up, realizing they want fundamentally different things out of life. Nevertheless, Harris tries to be happy for her mom and her aunt by standing up for Darlene as her maid of honor, in spite of the pain she's been through.

Harris' relationship with Aldo is yet another step in her ongoing rebellion against Darlene. In her five seasons on the show, the character has moved out of the Conner nest to live with a roommate (while underage), tried and failed to live with David, supported herself by baking edibles, and often found herself at odd with her mom, who really wants her to make it to college and avoid the mistakes Darlene made with David. In the Season 4 finale, mother and daughter are finally at harmony, but the possibility that Aldo might come back at any point still hovers over the family.
