Gloria Hickey is Danny Partridge's first girlfriend.
In Promise Her Anything but Give Her a Punch, Gloria is in sixth grade with Danny. She is a Girl Scout. Danny has a crush on her, but expresses his feelings by picking fights with her. Gloria has a crush on Keith Partridge and goes to the Partridges' house to ask him to the sixth grade dance. Shirley and Laurie Partridge unintentionally give Gloria the impression that Keith likes her back. Keith and Danny aren't in the room, so they can't correct her. Gloria comes back to the house later to try again, and this time both boys are there. Gloria asks Keith to the dance. Before Keith can answer, Danny tries to punch him. Keith grabs Danny's arm and says that he's not interested in Gloria because she's eleven. Gloria runs out of the house. Now she's in love with Danny because he fought for her. She goes back to the Partridge house and asks Danny to the dance. At the dance, the Partridges play I Would Have Loved You Anyway, and then Gloria asks Danny to dance. Then he walks her home. Both before and after they start dating, Danny and Gloria show their feelings for each other by hitting each other in the arm.
In Each Dawn I Diet, Gloria invites Danny to a swimming pool party, but says that he'll be the only one there with a natural inner tube. Danny goes on a diet to lose weight. During the party, Gloria judges competitions among the guests. Danny wins a trophy for Best Body. However, Gloria becomes annoyed at him because he won't let her eat sweets at her own party.
In You're Only Young Twice, Danny and Gloria go on a double date with Keith and Molly. Danny tries to act grown-up by eating egg salad sandwiches and sitting still with Gloria, who quickly gets bored. Before long he gives up and starts running with her. At the end of the episode, Danny and Gloria go to the Partridge house. They're about to play ball, but Laurie Partridge invites Gloria to look at some clothes she bought (to get revenge on Danny for monopolizing her dates earlier). When Danny objects, Gloria calls him immature.
In The Eleven-Year Itch, Danny pursues Julie even though he's still dating Gloria. By the end of the episode Danny and Julie aren't dating, but Danny plans to introduce Julie to Gloria.
As of Two for the Show, Danny and Gloria are apparently still together. Keith finds Danny writing a letter that begins "Dear Gloria, my love." However, a few episodes later in Danny Converts, Danny is trying to get a date with Renee Stern, with no mention of Gloria.
