Paradoxes; Harry and the Patronus - was another wacko theory

 <snip> This is the only way that I see that the events could have 
gone 
down: Harry's being attacked by the dementors by the lake.  Somebody 
other than himself with the patronus saved him.  It couldn't have 
been him; the only reason he saved himself when he went back in time 
was because he knew he'd already done it, which couldn't have been 
possible the first time the timeline played out (or he wouldn't have 
been saved and he wouldn't know to save himself.  It would be a 
paradox, and I have to argue because I don't like him.  He was saved 
because he saved himself and he saved himself because he'd been 
saved.  
It doesn't work.  You can't have both at the same time.
This is about where you could have probably made it a little 
shorter. You only need one person to pretend to be Harry/James and 
cast the patronus to save Harry, so he can go back in time, and save 
himself. 
This is just like the Terminator in that it's cool but sucks in 
reality.

What are you talking about?? This post makes no sense, so naturally, 
I had to object. From what you're saying, Harry has to be saved by 
someone else in order to go back and save himself, right? If thats 
what happened, why did he need to go back? The other person would 
still have saved him! 
This is my understanding of what happened: Harry is nearly 'killed' 
by the dementors, but at the last second, he saves himself, because 
he traveled back in time. He comes to, travels back, does all that 
other good stuff, and saves himself again. The one who is saved does 
the same. It extends on basically in an endless circle, with the one 
who is saved then going back and saving the one after him. Thats 
what happens when someone goes back in time, a whole other reality 
IMO. Which is why the ministry is so careful regulating these time-
turners. 
Before Harry goes back in time, the Harry before him has already 
gone back in time, and is waiting to save him. Did you notice how 
Harry THOUGHT someone else did it? Until, suddenly, it all hits him 
whats going on, he works it out and realizes it was him, so he 
stands up and does it. 
I'm sorry if I've confused anyone further or babbled too much, just 
wanted to see if I could explain it. How'd I do?
