Why do her 'real-world' brothers pretend to care? The mother is, and seemingly has been, openly abusing her verbally and through ostracizing her, and NOW they're talking her up?
There's a time and place for standing up for someone, and showing your love for them, and that isn't when they're practically already dead.
If she wakes up, I hope it's only to chew them out, before immediately relapsing forever and staying in the fantasy world.
Also, this better not be a
"it was all a dream" twist - they suck, they remove any meaning and purpose from a story, I will riot if it happens.
