No, but it suggests that Lesath might suspect Harry's involvement in the escape and have an interesting reaction.
I'm a bit disappointed that Harry hasn't noticed this, nor thought to ask what will happen when somebody has escaped Azkaban after a mysterious Dementor disappearance at Hogwarts... nor considered that Dumbledore at least should immediately suspect Harry's involvement, especially if any Dementors at Azkaban turn up missing.
What's more, if the Dementors are able to speak to the guards (as stated in ch. 51), then what exactly will happen when they report Harry's human-shaped Patronus?
Not considering any of these things seems out of character for Harry, his dreams of heroism notwithstanding. It seems he is making a huge mistake here, and preparing for a big change in his fortunes.
I'm beginning to wonder if Quirrelmort hasn't been planning all along to present Harry as "Voldemort returned", while he comes off looking like someone trying to protect magical Britain from this terrible scourge. He's spoken on the need for a Light Mark, and Harry publicly opposed it... which will look bad in retrospect.
[Edit: I guess I should've waited for ch. 53. Never mind.]
I'm uncertain of Quirrel's motivations here. It's possible that up-till-now has been Just According To Plan, and the plan is to blame Harry for attempting to break Bellatrix out of Azkaban, and hence utterly discredit him as a possible later rival. However, this seems a little much like a Xanatos Roulette; Quirrel could not necessarily have planned for the Auror he fought to be there and to react in the precise way he did, and he certainly could not have planned for Harry's Patronus v2.0 being able to block AK (and Harry wanting to do so), nor for Harry lo...
[Update: and now there's a fifth discussion thread, which you should probably use in preference to this one. Later update: and a sixth -- in the discussion section, which is where these threads are living for now on. Also: tag for HP threads in the main section, and tag for HP threads in the discussion section.]
The third discussion thread is above 500 comments now, just like the others, so it's time for a new one. Predecessors: one, two, three. For anyone who's been on Mars and doesn't know what this is about: it's Eliezer's remarkable Harry Potter fanfic.
Spoiler warning and helpful suggestion (copied from those in the earlier threads):
Spoiler Warning: this thread contains unrot13'd spoilers for Harry Potter and the Methods of Rationality up to the current chapter and for the original Harry Potter series. Please continue to use rot13 for spoilers to other works of fiction, or if you have insider knowledge of future chapters of Harry Potter and the Methods of Rationality.
A suggestion: mention at the top of your comment which chapter you're commenting on, or what chapter you're up to, so that people can understand the context of your comment even after more chapters have been posted. This can also help people avoid reading spoilers for a new chapter before they realize that there is a new chapter.
