My suspicion is that she’s either had an injury like a rolled ankle or something like that that put her in bed for a few weeks, a few more pounds and a bunch of swelling later, those legs ain’t getting that blob up and out of her room.
I think similar to Jae, when it finally happens, getting trapped in your house, then your room, by the hundreds of thousands of excess calories she stuffed in her face, it’s very jarring. Disturbing even. Jae in her last weigh-in video was gasping for air after 10 steps to the bathroom. She was far taller than Jackie. Jackie’s up a real creek and it’s probably set in in a way that she can’t muster that bubbly emotiveness she usually does. Nearing the upper 500’s, food her main comfort. Spiraling. It was always gonna get here.
