I've always had my doubts about the illness thing just because it's such a perfect excuse, you can't question or challenge it without becoming an instant pariah. That being said, it genuinely seems like she's having trouble settling back into her streamer voice and spends the entire stream floating somewhere between her streamer voice and just talking normal. If it had just been rust from her long absence I would have expected her back to normal within a few minutes but half hour in and the voice hasn't really changed, like she just doesn't have the energy to go full performance mode.
So color me less skeptical for once.
