History YMMV / DumbledoresArmyAndTheYearOfDarkness

* YouFailYourMedicalBoardsForever: The blood transfusion in [[http://www.fanfiction.net/s/4315906/10/Dumbledores_Army_and_the_Year_of_Darkness Chapter 10 of DAYD]], done without any attempt at cross-matching bloodtypes, and with two people donating blood, was quite risky, with about a 35% chance Colin would '''die''' from bloodtype incompatibility. Now, a 65% survival rate may not sound so great, but it isn't that bad for a dire emergency, and it is justified in that none of the characters are trained medics.
** The commonest blood type in the British Isles is O, which can donate to anybody, followed closely in England by A (not so closely in Scotland, which averages 51% O to England's 47%). There is about a 25% chance, possibly a little higher (since Ernie is Scots and Neville, as a Yorkshireman, is from the north of England) that both of them are Type O, with about another 12% chance that Colin is also. (There's about a 15% chance that both Neville and Colin are Type A and Ernie is Type O, and a 10% chance that all three are - and there's a 3% chance that Colin is Type AB, which can receive from anybody.) The Rh factor seldom causes problems unless an Rh- recipient has been previously sensitized by an incorrectly cross-matched transfusion or by an Rh+ pregnancy (neither of which applies to Colin). These odds help explain why early blood transfusion experiments were successful up to about half the time, with very primitive techniques and no real knowledge of what they were doing.

**** Yes, but Harry's Crucio was ineffective because despite the fact he was filled with hate for Bellatrix, seeing pain did not give him pleasure. Unless Thanfiction's arguing the Carrows are actually secretly nice people who don't enjoy hurting others, their Crucio's should be significant threats (Bellatrix's might be slightly better, but at that level of pain, does it really make a difference), not the badges of honor they are treated as in this fic.

*** When Neville gets hit with it at the hands of [[AxCrazy Bellatrix Lestrange]] he immediately notices the difference between being hit with a Cruciatus thrown by another student acting under orders, and being hit with a Cruciatus thrown by an ''expert'' in that spell. This harks back to ''Goblet of Fire'', where Harry tried to Crucio Bella, rather ineffectively.

** It's a pity neither Sporker finished the job. It would have been...interesting to see their take on [[BloodierAndGorier the DAYD version of the Battle of Hogwarts.]]
*** They've both finished now.

* SmallNameBigEgo: For [[http://forum.fanfiction.net/topic/46152/6034546/1/ example]]: ''The kind of love Michael and Terry have for one another is an extraordinary sort of brother-bond that men can form for one another under very rare circumstances, and it is one of the most powerful forms of love in the world, sometimes almost as strong as a mother for her child. That is something that I would find debased by making it into romantic or physical attraction, and that is why I am requesting that it not be done. Please respect this, and '''if I find out that someone has written a story from my canon that violates it, I will be reporting it to ff.net as uncondoned plagiarism.''''' So, he's going to report you for writing fanfic... of his fanfic... and claim it's plagiarism...

* TookALevelInJerkAss: Neville becomes more and more of a JerkAssStu as the fic goes on. See JerkSue up there.

** People cannot survive a hundred lashes, and then have it left untreated for days, without dying. This could possibly be justified by wizards' canonically superhuman durability (see also, Neville surviving being dropped out of a window without a scratch at the age of ten), were it not for the fact that blood loss from far lesser injuries is treated as a serious threat at other points in the story.
*** A lot of people have seriously misread this, possibly because the author did not make it sufficiently clear. It is forty lashes apiece, which is brutal but (just barely) survivable. It's more explicitly stated in a related one-shot, "Wisdom to Know the Difference". The lack of treatment is still too far Over The Top, though.

* CharacterDerailment: Snape. Keeping one's students safe by masquerading as TheQuisling generally doesn't involve gleefully participating in torture and active murder attempts, nor does it generally involve personally hiring a Dr. Mengele {{expy}} because the tortures so far have proven insufficient. In the books, it's implied that Snape curbed the worst of Amycus' and Alecto's excesses. Several other characters [[YourMileageMayVary have also been accused of this]], most notably Neville and Seamus (for JerkSue tendencies and [[{{Oireland}} Irish stereotyping]] respectively), but Hogwarts's shortest-serving headmaster remains the most dramatic and obvious example.

* RonTheDeathEater: Snape's portrayal is a debatable case. He's ''definitely'' more evil than in canon, but it's hard to say whether this was deliberate or accidental.

* RonTheDeathEater: Snape's portrayal could count as this.

* CrowningMomentOfFunny: Neville to Draco -- "Oh, and this is from Seamus Finnegan! [[spoiler: * KISS* ]]"
** That was the Crowning Moment of HoYay, more like.
* CrowningMomentOfHeartwarming: Neville, Ginny and Luna are being held in three separate cells in the Hogwarts dungeons. The Gryffindors have spent their confinement shouting themselves hoarse to no avail, while Luna has been using her food to ''fingerpaint'' the walls of her cell to resemble a bright cheerful garden of flowers. Before they leave, she uses magic to make the paint job permanent:
--> “I just focused on wanting it all to stay forever so the next person doesn’t have to be depressed.”
** We should point out that Luna's wand had been confiscated, so she performed all this using a '''spoon''' as a substitute.

* HighOctaneNightmareFuel: Oh ''where do I begin!?''

-->"BAM! Other side of his face goes, and Alecto was so furious, she kicked him out of the class. Said he had lost the privilege of learning from Belsen. So that's when I raised my hand and asked if I could lose the privilege too, and Belsen just gave the whole class this long look, looked back at Alecto, and told her that he had been under the impression the teachers controlled Hogwarts, not the students, and he left." -- Jack Sloper describing the surprisingly quick defeat of Nazi torturers.

** I fail to see how it's all that out of character given the Snape from the books. We see that Harry eventually decides he's brave and noble and whatnot after the dude is dead, but all through the novels we see him engaging in pretty much outright sadism towards Harry, for no real reason, and he had been a Death Eater up until the Voldemort threatened the girl he was obsessed with. Snape may arguably have redeemed himself in the end, but if we knew his backstory he had undoubtedly done terrible things as a Death Eater, and he wasn't exactly ever a good guy.
\\
Granted, he's never depicted as quite that evil in canon, but it fits with the generally darker tone of this particular fanfic.

*** The point was, Snape was indeed a prat, but he was never a sadistic "I will Crucio your ass to next Sunday" prat. As mentioned, Snape tried to curb the atrocities at Hogwarts, not make them worse. Which is why this section is even here.\\

* TheyWastedAPerfectlyGoodPlot / ShaggyDogStory: Chapter 18 of DAYD. Hans Belsen, basically an Expy of Josef Mengele, shows up to the school because he wants to torture children. When [[GaryStu Neville and Jack Sloper]] insult him ''later that chapter,'' [[WallBanger he immediately leaves the school instead of, you know, torturing them.]]

* CompleteMonster: Severus Snape. As Headmaster, he inflicts his sadistic whims on the poor students and regularly blackmails the D.A. by punishing '''eleven-year olds''' in their place. He even ordered an eleven-year old flogged and left in chains for thirty hours. What Snape did to [[spoiler:Michael]] as a punishment for freeing this kid was completely unforgivable: he had the poor guy tortured in a nightmarish way, prolonging the agony to the point where his best friend Terry tried to put him out of his misery with ''Avada Kedavra''. The author has been criticized for portraying Snape as way, way too evil.
