Did she predict the number of Harry's children or him being Minister?
In case nobody has answered you yet, she had. In OOtP, after HP's interview came out in The Quibbler, the teachers displayed their approval in various ways. During HP's Divination class, which was being overseen by the evil Umbridge, Trelawney weepingly told the class that HP wasn't about to die, he would become the youngest ever Minister of Magic, and he would have 12 kids. I thought it was hilarious.
Speaking of Umbridge...I know Sirius was certainly right in saying that the world wasn't divided up between good people and Death Eaters, but Umbridge's continued support of the Ministry--fervent support--well, she may not have been a DE but she certainly was in collusion with them. I was really looking forward to seeing her die.
