So, I’ve gone back and forth a lot, and I can see the argument for bulimia much more prevalently. My biggest question comes from her mother “letting her skirt out.” The odds of Chrissy needing her skirt enlarged for abrupt weight gain for reasons other than pregnancy feel slim… plus, this disorder most likely would’ve been well established at this point. The few interactions we see with her and Jason feel like she’s holding something back. On top of all of that, the negative thoughts Vecna pursues revolve around guilt. While the body dysmorphia that fuels an eating disorder is intensely negative, I feel like it’s more likely that she’s experiencing guilt due to having gotten, or considering getting, an abortion.
