The phrase dodgeball girl refers to an unnamed girl who goes to the same school as Becky and Tobey. She receives special focus in one episode where she stalks Tobey, having traumatized him over his dodgeball defeat that he wants to make summer last forever so he doesn't have to go to school and face her again.
She is later seen within the audience of the concert, visible behind Becky and TJ in the space between them. Steven (WYFW) is sitting to her left side, and a blonde woman in a green jacket is sitting to her right side. Lesly is sitting over her right shoulder.
