Order of the Phoenix: Harry and the Killing Curse

(The following is my take on things. If anyone can think of anything better...)

KILLING CURSE -

The killing curse (Avada Kadavra) is one of the unforgivable curses, outlawed by the ministry of magic and holding a lifetime sentence to Azkaban for its use on humans. There is no known counter to the curse which kills its victims instantly in a flash of green light and the sound of rushing wind, leaving no visible mark or cause of death. Only one person (Harry Potter) is known to have survived the curse.

HOW HARRY SURVIVED THE KILLING CURSE (first draft) -

THE FIRST POINT:
Wizard children (those children with magical abilities) have been known to unconsciously use magic when frightened, or angry. Harry transported himself to the school roof when Dudley and his gang were after him. He also made the glass vanish from the snake cage at the zoo when mad at Dudley. Neville made himself bounce when he was dropped from a second story window by his uncle. These things happen, seemingly, without the children actively trying to do them. They seem to be an accepted part of growing up with magic blood. In fact, parents (and others) think it quite strange if occurrences such as what happened to Harry and Neville don’t happen at some point (I feel quite sorry for muggle parents). Children go to school in order to learn to control the power they have, not to acquire it (at least this is mostly the case).

THE SECOND POINT:
A wizard’s ability to do magic depends on the amount of power they hold. Some wizards can’t do certain spells because they aren’t powerful enough. These types of spells are usually considered advanced magic. For example, the patronus charm is considered very advanced magic (up until the fifth book) and very few wizards can actually do it (or they have problems doing it), even more so have the charm take an actual recognizable shape. The same goes with the killing curse. A great deal of power must be behind it to make it work (most students wouldn’t have the skill to do it). So, the more advanced the magic, the more power is required to do the magic.

THE THIRD POINT:
In my (my being Tracy) version of the Harry Potter universe Harry is as strong (or capable of becoming as strong) as Voldemort, with Dumbledore coming in a close second. In other words, Harry and Voldemort are slightly more powerful then Dumbledore (known to be one of the most powerful wizards of his time). So, Harry should be capable of doing some very advanced magic (intentionally or unintentionally).

THE FORTH POINT:
It is thought that there is no way to block the killing curse. Most (if not all) would say it has no counter curse. The only way to avoid it is to duck. A more proper way to say it would be that there is no KNOWN counter curse. It seems reasonable to state that just because no one knows of a counter doesn’t mean one doesn’t exist. It also seems reasonable to state that a counter to the killing curse would be extremely advanced magic. It would take as much, if not more, power then that being used on the killing curse to affectively use the counter curse (if one did exist).

[ begin note:
How are curses and counter curses discovered? From what we have seen, it is done by experimentation. How then would the counter curse to the killing curse be discovered without someone getting killed in the process? Would someone try to block it when it wasn’t aimed at them? It seems like part of the counter curse would be the extreme desire not to get killed. Can someone, than effectively experiment when they aren’t in danger of dying? How about practicing the counter curse? Wouldn’t the same problem apply? Just some thoughts.
end note ]

CONCLUSION:
Harry blocked the killing curse. All that happened (the scar, the transfer of powers [or connection to Voldemort], the destruction of the house, the death of Voldemort, etc.) was the result of the counter curse.

NOTES:
Remembering that the killing curse actually touched Harry (or so it seems), I was thinking a little more about how blocking it would actually work. It doesn’t seem like it is blocking it in the traditional sense if it actually touches the person. Nor do I think it is reversing the killing curse. It would seem like, then, that there is a split second right after the curse hits and before the person is actually dead when it is possible to block/reverse (or expel to use another term) the curse. It would also seem likely that only the person being hit with the curse could accomplish this (or maybe I think it is very convenient for me if this were true). It would make sense. All attempts to block the curse before it hits a person have failed. There is no known spell to bring back the dead. Both of these things have probably been looked into a great deal. What if, then, the defeat of the killing curse lies somewhere in between?
