I think she is sick because her complexion isn't really good... she looks pink at the end!
And she has gained weight~ it's good.
I think we are hearing two different performances, because I don't think it was that good.
They just put the volume up on her vocals so we can hear them clearly.
She is still horribly offkey...
It sounds like she has no energy... she has to sleep!
That's part of the reason she can't give the best performances.
She never sleeps! D:
