How incredibly sad. I've never met Angela or her mother, but people I've talked to at various competitions always mentioned her mother as such a nice person.
I sent a note of condolences on Angela's site and hope many more GS members do too.
As for a bye to worlds......I doubt that Angela would want to go or would accept under the circumstances. And I wouldn't be surprised if this marks the end of her competitive career. I hope it does not, but we have no idea how this will affect this remarkable young woman.
Now, the ISU should certainly invite Angela to compete in next season's Grand Prix. After all, she was the gold medalist at Skate America.
I know it's selfish, but Angela, your fans would like to see you skate again.
