I'm playing devil's advocate here but she does have a very nice body and by going to the gym regularly to train her muscles doubt she's going to go back to looking skeletal again,
But reg. the spectrum comments she's def OTT especially in the car, I guess just not how I would expect the oldest sibling to act. The tiktoks are weird and how she strips off her clothes, ugh lmao.
But she has clearly worked hard on her body it'd be a shame to see her relapse if she does. I also noticed her mum isn't as around much in her videos anymore.
