In When Love Takes Over, Sadie is introduced when Dave strikes up a conversation with her about Sweetheart Week. Dave musters up the courage and asks Sadie on a date to The Dot. She accepts, and Dave excitedly drags Connor DeLaurier and Wesley Betenkamp over to the library so he can show them Sadie, who they find out is about a few inches taller than Dave. At The Dot, Dave finds that he and Sadie have a lot in common, but when she stands up to get coffee with him, he freaks out and tells then her to wait at the table. The next day, when Sadie asks Dave about their upcoming date, he cancels on her and then proceeds to make fun of her in front of Wesley and Connor. Sadie hears him, gets mad at him, calls him a "jerk", and storms off with a group of her friends. Later, Dave finds her on the court playing basketball with a group of girls. Sadie is still mad at Dave, and he tries to convince her the comment was a compliment. He wins, but wants to make it up to her for mocking her height. Dave makes a bet with her - if she wins a game of basketball, then they don't go out, but if Dave wins, he gets to go out with her. At the end of the episode, we don't know the score, but Dave makes the final shot, and the two walk away hand in hand, hinting that he most likely won.
In The Way We Get By (1), Sadie is seen at the game, cheering along with her friends. After the game, Dave puts his arm around her and asks if they should go see a movie. K.C. mentions the last time they did, they could barely watch the movie because they were making out. Sadie and Dave go out and hang with K.C. and Jenna, leaving Drew behind.
In Cry Me A River (1), Sadie, as Dave's girlfriend, pushes him to go ask Sav if he has won the job of having a one man show on Degrassi Radio. Later on, once Dave discovers he has to go on air with Adam in order to let the school decide who they want for the gig, Dave tells Sadie he can't lose to Adam of all people.
