I remember these going by; will reread tonight and reply if necessary.

Amanda-now:
My point exactly. The author has not written it. Sirius *died.*

Amanda-now:
But he *did* die, so we know it didn't work--unless he was snatched 
by our rescuers and taken somewhere. Character reaction in canon, 
though, makes it pretty clear that going through that arch is fatal, 
even if the spell didn't kill him to begin with.

Amanda-now:
I am pretty much *completely* not following you. 

If an attempt had been made--that in the future, if they decide to go 
back in time to make this attempt--then we, viewers of the event 
the "first" time, would have seen the effects of anything the 
rescuers did. We may have. My point is, if they did, it didn't work, 
because the past we remember has Sirius dying in it. 

We cannot go back and experience a new "past." It has occurred; if 
future rescuers were in it, they failed.

Amanda-now:
We are indeed reading the same book. This is what "interpretation" 
means. We are extrapolating different theories from the same 
information. 

I'll read the earlier posts tonight. I think when they went by 
originally, I was time-turnered-out.
