saying, "Nope, there's no hope for THAT one."  But surely there's at 
least one other person out there who can't quite grasp this!?  Damn--
I'm Phi Beta Kappa, but I can't "get" time travel!!!]"

That one would be me.  I've stayed out of TT threads for this very reason.  I cannot wrap my head around it.  However, having just read this thread, reading what PK wrote above, I had one thought:  What if the voice HP heard at GH and thought was James was actually himself?  Is that why Lupin was so shocked when HP said he'd heard James' voice (during the Patronus lesson)?  Has HP already gone back to GH, told Lily about the 'ancient magic' of sacrifice to save baby-Harry?  

Grasping at straws because I just don't get it...
