Not that it's important in itself, but it's an important piece of discovery, and foreshadowing, that an event that just happened has more effect that anyone realized: the magic is picking up and doing a lot more than it used to.
Which means, of course, that I have to figure out what, exactly, is happening. Lamps lighting themselves? Fires lighting themselves? Dusting occurring on its own? (Not to mention that might just prove significant in itself later.)
And all told from a point-of-view of someone who neither gets the full meaning of it nor even really understands the reactions of those about her to it.
