Chp 39 (the Dementor)

I think that Dumbledore and Harry were too quick to conclude that the Dementor could just be used as a distraction. It was Harry's first idea (once he turned cold), and Dumbledore stopped him there. Cold!Harry didn't even spend 5 minutes on the problem - compare with Harry's instructions to Fred & George in the Hold Off on Proposing Solutions MOR chapter. If there's a plot, that seems much too obvious for Quirrell.

What immediately occurred to me (similar to the infamous scene in The Princess Bride), is that if your opponent believes you will have a distraction and a real attack, simply lauch two real attacks, with the expectation that whichever one the opponent takes to be the distraction will succeed. Obviously this requires a greater sacrifice of materiel, but Quirrelmort doesn't exactly seem short in that department.

Do one better. Have an obvious distraction, a less obvious distraction, and one real attack. That way, when your adversary discovers the less obvious distraction, he'll stop looking.

Why would you ever have only one real attack? I could see an argument for maintaining a 2:1 distraction:attack ratio, but you should never hang all your hopes on a single plot.

He appears to be working with much less than his former amount of magical ability.

Canon!Harry was especially vulnerable to Dementors, which raises the possibility that the Dementor is there to influence Harry's personality, increase Quirrell's hold over him, and shape him into what Quirrell wants him to be. Dumbledore described Harry as having a mind like a Dark Lord but with love which makes him non-evil, Dementors suck out love & happiness. And Dumbledore is supposed to be the one protecting him, so if anything bad happens to him....

True, and somewhat understated. Dumbledore defeated Grindelwald and led a hard fought defence against Voldemort and his death eaters. Why on earth does he need to call in an eleven year old with magic cold/angry powers just to come up with the thought 'maybe it is a distraction'?

This Dumbledore has been crippled to beyond all recognition.

Two possibilities:

  1. Dumbledore has been too busy to step back and think about the situation creatively.

  2. Dumbledore is making up a reason to invite Harry Potter into his office to (a) get his report on Lucius Malfoy, (b) warn Harry about the Dementor coming onto campus, (c) encourage Harry to practice his cunning outside the formalized exercises of Quirrell's armies, (d) lend credence in Harry's eyes to his suspicions of Quirrell by revealing that Quirrell is acting suspiciously, (e) query Harry about Voldemort.

I do not find either entirely implausible.

I agree with (2). I could quibble over the subpoints, but it comes down to: to get Harry's reaction.

Using a Dementor to weaken Dumbledore seems like an alternative explanation.

How much does Dumbledore trust the Auror backup he'll be getting?

He should be able to trust Kingsley Schacklebolt.
