Tigerheart and Dovewing's parents are Rowanclaw and Tawnypelt. Rowanclaw is a ThunderClan warrior while Tawnypelt is a ShadowClan warrior, making Tigerheart and Dovewing siblings from different clans.

In book two of the Omen Of The Stars series Russetfur does in fact die at the end of the book. And in the new Warrior's Special Edition book the new ShadowCan deputy is Rowanclaw. We all know that Blackstar is a old kitty now and may retire soon or loose his final life soon in the next couple of books to come.

That's a prediction that is most likely going to happen if the series doesn't end before that.
