I wrote a R/T fic before the release called Mentors. When I wrote it, only one character in that fic was already dead in the books. Now, only one character in that fic is ALIVE. The other four are DEAD.
In other news, it comes as no surprise to me that JKR didn't intend to kill Remus and Tonks. That explains the COMPLETE LACK OF EXPLANATION. But I'm torn: on the one hand, I'm happy Arthur's alive but on the other... Remus and Tonks were meant to live! Damn you, Jo... ;_;
