If Du read the Insider's Guide, J.R. always says that her characters are real. They do what they want and she just writes it down. I think that V doesn't like her because she lied about something. I dont know what it is though. When the Brothers interveiw her, V askes "Why did Du lie?" I think something was supposed to happen but she didnt put it in the book and that made him mad.
V's sight has been both a curse and a blessing but mostly a curse. He can "see" the death of all his brothers just not when. They're always incomplete...by J.R. giving him these "gift" she's pretty much left him in a proverbial rock and a hard place. He knows what's going to happen in the Weiter Bücher in the series and czn't do a thing to stop the bad frm happening he's just along for the ride.
