Love Triangle History
Although Dave had been in a relationship with Sadie for months, his former feelings for Alli returned. Sadie began to feel jealous of Alli and Dave hanging out, and upon realizing that Dave liked Alli, she publicly dumped him. Shortly after, Dave asked out Alli, and she accepted.
In Should've Said No (1), Dave and Alli are part of the Grade 10 representatives and have to plan movie night. They are walking through the halls (and also point out Marisol and K.C. flirting) and discuss which movies they could watch. Alli points out that she misses hanging out with Dave, and he asks what happened. Alli tells him that Drew got in the way of things and her first semester was a bit rough. She then asks if he would want to go out for some wings with her later, which Dave agrees to. After Dave is at The Dot with Sadie, she asks him if he wants to go to couples fondue night later, but remembering his plans with Alli, Dave tells her that he is going to Adam's place to hang out. Later at The Dot, Alli and Dave share wings and are having a good time, until Marisol walks in. Although they're out as friends, Marisol points out that they are there on couples fondue night, Dave realizes that he told Sadie that he couldn't go because he "had to go to Adam's house". Feeling awkward and guilty, Dave apologizes to Alli and leaves.
In Should've Said No (2), Sadie is seen talking about basketball with Dave but he leaves her to go help Alli with a banner. She is next seen at Movie Night waiting on Dave and when he arrives she attempts to kiss him, but he backs away and looks at Alli. She discovers that he has feelings for her, but he defends himself by saying he didn't cheat. Angry, she makes a scene in front of everyone, calling Dave a lying, cheating pig. She throws her popcorn over him and storms out, as the girls in the theater applaud her.
