If that's the case, why her parents didn't offer her tutors before, for instance when she was so obviously struggling with her dissertation that it took her something like 20 drafts (the last one being finished 20 minutes before submission apparently)? Why aren't they offering her therapy now, when it's also obvious that she suffers from an ED?
Her parents (at least her mother) always seem to bury their head in the sand when it comes to Ruby: as long as the cash flows from YT, they consider their daughter happy & thriving.
Also, she doesn't work that much: she pretends to be working. Using four different planners in which to write down her assignment won't help her write them, and without someone like Blakeney she'll be totally lost and will have to forge brand-new routines if she wants to stand a chance.
However, we all know how rigid Ruby is about change... Her routines are the best because (1) she's the cleverest person on earth and forged them herself; (2) it helped her get a degree from Exeter (never mind Blakeney, we know she's the main reason Ruby graduated, but we're the only ones). So I can't see her changing a thing.
She'll probably be utterly happy for a few weeks, until she realises that she's in another environment and won't be able to reproduce her usual habits to succeed without trying too much. And then, she'll be miserable.
