While it would be fascinating to log all the spells and potions used or mentioned in
Harry Potter, it probably would not yield as much food for discussion as we might wish when it comes to our purposes of looking at dramatic set-ups and payoffs.
There are a few spells and potions, however, that have had ample set-up and maybe not quite the corresponding level of payoff yet, so I'd like to focus on those. And first and foremost, we have to look at the
Unforgivable Curses, especially the Imperius Curse and the Cruciatus Curse.
The Imperius CurseThe Imperius Curse has given the Ministry of Magic trouble in the past, we learn from Fake-Moody in
Goblet of Fire [GF-14]. Back in Voldemort's first heydey, the Ministry couldn't figure out who was doing bad things out of their own free will, and who had been Imperiused into doing them.
We get a set-up in
Order of the Phoenix that we might be in for some Imperius action soon when Harry wonders if the Death Eaters have put the Imperius Curse on Lucius Malfoy [OP-9] -- just a nice little mention, something to remind us that this Curse, which allows the spell-caster total control of the victim, is still out there, still a threat.
And that little set-up gets a pretty full payoff in
Half-Blood Prince when Katie Bell is Imperiused to get her to carry the deadly necklace into Hogwarts [HBP-13]. We actually learn quite a lot about the Imperius Curse if we look at this incident closely.
First, we learn later that Madam Rosmerta was the one who cast the curse on Katie -- but Rosmerta was herself under the Imperius Curse at the time! This tells us that someone under the Imperius Curse can actually
cast the Curse, which would seem to allow the original spell-caster enormous amounts of power.
We also know that, in
GOF, Victor Krum was Imperiused into performing the Cruciatus Curse on Fleur during the Third Task [GF-31]. Can we therefore assume that someone can be Imperiused into casting the final Unforgivable Curse -- Avada Kedevra? If so, the caster of the Imperius Curse is in a position to go around killing people without ever being linked to the crimes (go solve that one,
CSI!).
I wouldn't be surprised, given these two set-ups, if we see exactly that in Book 7: Someone Imperiused into performing Avada Kedevra. Should we see an unexpected murder, from an unexpected source (say, Percy, leaps to mind), let's keep that in mind.
(Did we already see just that in Snape's killing of Dumbledore? I would say not. I think Snape knew exactly what he was doing -- even if
we may not know exactly what that was yet.)
What else do we learn about the Imperius Curse from the Katie Bell/Madam Rosmerta episode? Well, we learn that the spell can have some duration, and that the spell-caster doesn't have to be physically present for the spell to continue to work (as Fake-Moody was present when Victor was Imperiused). No wonder the Ministry had so much trouble sorting things out!
Another lesson from this episode, and one that our characters would do well to heed: We now know that when someone is Imperiused, it's important to sit down right away and figure out who did it. Hermione is on the right track when she figures out that it must be a woman who cast it, given that Katie Bell received the necklace in the ladies' room of the Three Broomsticks [HBP-24]. But she shouldn't have let it sit there! If only everyone had thought through what Hermione just said, and moved on to ask the obvious question: What woman is most likely to be in the ladies' room at the Three Broomsticks?... the cursing of Madam Rosmerta might have been solved much earlier.
Dumbledore does figure it out, of course, moments before his death [HBP-27]. But it's a little late. Let's hope the characters learn the lesson we've just learned: When someone is under the Imperius Curse, figure out who cast it!... A potentially important lesson, if indeed Book 7 fills out the 1-2-3 pattern set up in
OOTP and
HBP, giving us someone casting Avada Kedavra while under the Imperius Curse.
We also learn from the Rosmerta episode, incidentally, that Draco Malfoy is a much better wizard than we might have expected, to cast an Unforgivable and get such exact behavior.
Or is it that Draco is just average, and the problem is that Rosmerta is especially weak?
This matters, because while the Imperius Curse may be Unforgivable, it is not unbeatable. We learn from Fake-Moody that people with strength of character
can fight the Curse (while those without strength of character cannot). We see the set-up that Harry
can fight the Curse right away, when Fake-Moody teaches it [GF-15]. This set-up is of course paid off when Harry manages to fight against the Curse with Voldemort himself casting it in the graveyard [GF-34].
This gives a hint we can use if it turns out that we have Imperiused people running around Book 7. Who is weak enough to be used and manipulated in this way? (Again, Percy comes to mind. Also Slughorn. Trelawney. Pettigrew. Crabbe and Goyle. Go ahead, add to the list.) It also can help us figure out who would
not be Imperiused -- McGonagall, Neville, Snape. Anyway, this is something to keep in mind for Book 7.
It is interesting, by the way, that Harry can fight against the Imperius Curse, and he seems to have beat back Avada Kedavra as an infant, but he appears to be helpless in the face of...
The Cruciatus CurseThe Cruciatus Curse has a special appeal to Harry from the moment he hears of it. Only four chapters after first learning about it, he begins to fantasize about perfecting the Curse on Snape, in response to Snape's having given him detention [GF-18]. (A nice set-up for his later attempts to cast the Curse on Snape in
HBP!)
Harry is nonetheless shocked to see Victor perform the Cruciatus Curse on Fleur in the Third Task [GF-31] -- again, anice set-up, because it gives us a chance to see what happens when the victim is a human rather than a spider. We also begin to learn in
GF and much more in
OOTP what the consequences of the Cruciatus Curse can be, as we learn about and see the insanity of Neville's parents.
The Cruciatus Curse is Harry's go-to when he wants to really harm someone he hates. He tries it first on Bellatrix in the Battle at the Ministry:
Hatred rose in Harry such as he had never known before. He flung himself out from behind the fountain and bellowed " Crucio!"
Bellatrix screamed. The spell had knocked her off her feet, but she did not writhe and shriek with pain as Neville had -- she was already on her feet again, breathless, no longer laughing. Harry dodged behind the golden fountain again -- her counterspell hit the head of the handsome wizard, which was blown off and landed twenty feet away, gouging long scratches into the wooden floor.
"Never used an Unforgivable Curse before, have you, boy?" she yelled. She had abandoned her baby voice now. "You need to mean then, Potter! You need to really want to cause pain -- to enjoy it -- righteous anger won't hurt me for long -- I'll show you how it is done, shall I? I'll give you a lesson--"[OP-36]
We hear much the same response in
HBP when Harry tries to use the Cruciatus Curse on Snape, and Snape blocks him:
Twenty yards apart, [Snape] and Harry looked at each other before raising their wands simultaneously.
Cruc--"
But Snape parried the curse, knocking Harry backward off his feet before he could complete it; Harry rolled over and scrambled back up again as the huge Death Eater behind him yelled, "Incendio!". Harry heard an explosive bang and a dancing orange light spilled over all of them: Hagrid's house was on fire.
"Fang's in there, yer evil--!" Hagrid bellowed.
"Cruc--" yelled Harry for the second time, aiming for the figure ahead illuminated in the dancing firelight, but Snape blocked the spell again. Harry could see him sneering.
"No Unforgivable Curses from you, Potter!" he shouted over the rushing of the flames, Hagrid's yells, and the wild yelping of the trapped Fang."You haven't got the nerve or the ability--" [HBP-28]
(Note, by the way, that Harry, perhaps unconsciously, follows Snape's advice. He next tries to cast Incarcerous, Stupefy, Impedimenta, Sectumsempra, and Levicorpus -- but he does not try an Unforgivable again.)
From these two incidents, we learn that blinding hatred isn't enough to successfully cast an Unforgivable -- because Harry certainly has enough of
that to go around in both cases! Apparently one needs nerve, ability, and the enjoyment of causing pain to successfully cast an Unforgivable... And note, by the way, that Draco
does have the prerequisites.
Will Harry successfully cast the Cruciatus Curse? I think that depends on what "Unforgivable" means.
So far, all we know is that casting an Unforgivable Curse on a human lands one in Azkaban. But that's a pretty strong term for a life-sentence crime. Is there something more about casting an Unforgivable Curse? Who is refusing to forgive? Is it just the Wizengamot? Or are there deeper, more spiritual consequencs of casting an Unforgivable?
We know from Slughorn's memory about Horcruxes that
"Killing rips the soul apart. [HBP-23]" This tells us that casting the Avada Kedavra does indeed cause harm to the spell caster. But is this true for all the Unforgivables? Would it harm Harry's soul in some way to successfully cast "Crucio"?
I don't think the answer to the question necessarily makes our predictions for Book 7 any easier. If the answer is "Yes, it would harm Harry's soul," I don't think that would prevent J.K. Rowling from having Harry successfully cast it. As Harry's face is scarred, so his soul could be scarred by the successful casting of an Unforgivable -- a consequence he would have to live with and deal with.
So I don't know if Harry will
land "Crucio" in Book 7. But I would bet a large sum of money that he will try. And given that once again we have a 1-2-3 pattern (of set-up/set-up/payoff -- just like in any good joke), I would expect that he
will successfully cast it. (Not on Snape, is my guess. I don't think Harry can beat Snape wand-to-wand. My bet would be Draco.)
One last Unforgivable Curse to give at least a quick glance to:
Avada KedavraWe have all realized, haven't we, that "Avada Kedavra" is etymologically related to "abracadabra"? As a former linguist, I have to mention it.
I think we actually have very little in the way of set-ups for Avada Kedavra in Book 7. We do have questions to be answered: How did Harry beat the Killing Curse as an infant?
But I can only think of two potential set-ups involving the AK. One I mentioned above: The fulfillment of the pattern of Imperiused wizards casting Unforgivable Curses. The other involves Draco's inability to cast the Avada Kedavra on Dumbledore [HBP-27]. I suspect that we may see Draco try again. Whether he succeeds depends, I think, on his redeemability. If we see him succeed, we will know that his soul is indeed, "ripped apart," and I would expect we can count on a very bad end for Draco.
And Draco is who we will turn to in these posts, as soon as we wrap up just a few more Spells and Potions of interest.... Coming soon...
