Hm... nicely, yeah, logically that could have been extra effective. yet Harry became into in Gryffindor,formidable, nerve and chivalry set gryffindors aside, not Ravenclaw, the clever ones that would have seen that, lol. additionally, the exterior of the lake/pond became into frozen, so it would have taken an prolonged time to get soften the ice, and then initiate warming the water under, and it became into wintry climate time, and it became into freezing exterior, so i don't understand if Harry could have finished plenty, he could have melted slightly the ice, yet i think of it became into so chilly exterior, that he could not have finished plenty. i'm valuable there's a extra useful spell to make warmth come out of the top of your wand, somewhat like the single Hermione used to soften countless the snow, however the ingredient is, it is extra of a Hermione-ish spell, in case you get me. Harry could not have taken plenty time to comprehend it, and Harry is chivalrous so he did not bypass ask Hermione to end this activity for him. i think you're right nonetheless he could have been waiting to do something to make the region somewhat extra effective, even nonetheless it would not have been very exiting in case you study "Harry sat by way of the pond for an hour warming the water" might it? besides, i think Harry became into brave to bypass plunging into the chilly water, and it made for an exceedingly exiting tale. and in spite of if he had warmed the water first, the locket might have tried to strangle him, yet in heat water, it would not have had the comparable element. nicely finished for thinking this one out, yet i don't think of Harry became into the kind of guy to attend until the water became into heat and delicate before retrieving the sword, he became into formidable, brave and chivalrous, a gryffindor, and not a clever ravenclaw who might have theory it out. :) superb question, i'm going to superstar it.
