It’s two, seemingly nonchalant lines than any casual viewer would overlook. But it’s so much more. Zelda Fitzgerald had a lot of talent. Scott was misogynistic, possessive, and selfish. She was his muse and I believe he did truly love her, but he didn’t respect or support her standing as her own woman. She tried so hard to find her own calling, something that she could do well that he would appreciate as much as she did. Zelda tells Gil she’s talentless, and instead of correcting her, or saying that she’s simply being modest, Scott confirms the horrid self-deprecation that consumes her— that’s she’s nothing to the world, and eventually, she’ll be nothing to Scott because of that.
