The Conflict: "The Director's Daughter"
The Motive: Puck and the football team likely view her as a "narc" or a teacher's pet by default. To them, she represents the authority they rebel against.
The Slushies: In classic Glee fashion, Ellie becomes a frequent victim of the grape slushie. Hailee Steinfeld's portrayal would likely lean into the "silent endurance" style-wiping the syrup off her face with a tired, "is that all you've got?" look that actually infuriates the bullies more.
The Wedgies: This adds a more aggressive, physical humiliation aspect. It highlights her isolation; because she's Will's daughter, she might feel she can't tell him for fear of making him look weak or causing him to lose his job by overreacting.
