Sirius and the Two-Way Mirror

There are different theories with this and I would like to hear everyones take upon this. Obviously it will be recognized in the seventh book because JKR will not answer one snippet of a question that is turned towards this mirror. We can talk about the days that it was used for James and Sirius *sighs* and what would have happened if that Potter boy would have actually used it? *ish a little touchy on that subject but I still love Harry* Would Sirius have been alive today?

Sorry I have not started this before now! *dies* I did not realize that it was time!

YAY! First to post!

Well, in book 5 it says James and Sirius used the mirror to communicate when they were in different detentions. I guess its use might also have extended to the days when Voldemort was powerful and both of them were in the Order... that would have been pretty useful. What I am curious about is whether such two-way mirrors are common in the wizarding world or whether this, like the Invisibility Cloak, was another of James' rare possessions (where did he get them all??) We don't even know whether the pair belonged to James or Sirius... I wonder why JKR doesn't want to answer our questions about it? Maybe it's a really crucial part of book 7... *dies in anticipation*

About Harry not using the mirror... well, I really believe Sirius would be alive if he had used it. Though since Harry is noble to a fault, it might have been kinda out of character to make him use it after he'd promised himself not to and had even forgotten about the mirror altogether. I mean, I'd forgotten that Sirius had given him that package until it reappeared at the end, so you could hardly expect poor Harry to remember it while stressing about his vision of Sirius in the DoM. I see Harry's nobility - or, as Hermione puts it, his "saving people thing" as a tragic flaw which causes him to indirectly hurt people he's trying to help. And without that flaw, he wouldn't be the Harry we know. So I guess Sirius had to die... *rushes off to bribe Bloomsbury to change the book anyway *

No, I doubt he would still be alive. He was too close to Harry, which made him a threat to Voldemort. He would have died somehow.

Sirius might not have had the mirror with him, in which case, Harry would have judged him to be in danger.

I think that when you are desperate to do something, you don't stop and think about all the things you could do. Harry was panicing when he saw that Sirius was in trouble, and he used the method he first thought of. So there was a very small possibility that anyone would have thought of that. Maybe even JKR forgot about it? Who knows...
