[[WMG: There are actually ''two'' Winter elementals and two Summer elementals.]]

Because the Literature/{{Discworld}} isn't a sphere, its seasons aren't derived from planetary tilt; rather, the parts of the rotating Disc that are nearest to the orbiting sun's overland path experience summer, and the parts that are perpendicular to that path have winter. That means that there's ''two'' areas of Disc that undergo a winter, and two that have summer, at any given time, as the seasons progress Widdershins around the spinning world.

The young-seeming and (initially) immaterial Wintersmith whom Tiffany Aching meets has a counterpart: the elderly-looking, icicle-bearded Jack Frost, who'd previously appeared in ''Literature/{{Hogfather}}''. It's the ''latter'' whom the illustrator had been thinking of, when he drew the Spirit of Winter for Miss Treason's book of mythology, not realizing that there were two of them. Likewise, the Lady of Flowers and Summer Lady aren't actually the same person, although most Discworld mortals tend to conflate them.
* This seems almost completely confirmed by early Word of God, as the Discworld has always canonically had eight seasons (remember the importance of eight on Discworld?).

[[WMG: Lung damage is what causes Annagramma's thunderous snoring.]]

Annagramma is extremely proud of her ability to create fireballs out of her bare hands. Fire creates smoke, and prolonged exposure to smoke causes lung damage. What if Annagramma, being Annagramma, used that spell more than she should've, even when she knew it was damaging her? What if that damage is what causes her deafening snoring?
* This also creates a nice Aesop, in that Annagramma used her pride as a shield against her shame, but in the end, it didn't help her escape shame; it just buried her even further in humiliation.

[[WMG: The Feegles being purple makes sense for this cover.]]

It's a common complaint that the Feegles are depicted as purple on the covers of the Tiffany Aching books when they should be blue, but for this book, it's logical. They're in blizzard conditions, so their rates of blood flow will be higher than normal. Mix the red of their blood and the blue of their skin and viola: violent violet.
* Although the Feegles' skins are only blue because of an overload of tattoos, I like to think that they really are born looking like they took a swim in paint.

[[WMG: A simple and boring one: Annagramma is extra-condescending to Petulia because she is jealous of her.]]
'''Note:''' This is an ''explanation'', NOT an excuse. Petulia deserves '''none''' of the crap Annagramma throws her way.\\\

She's jealous for two reasons:
* [[AddedAlliterativeAppeal Petulia's prominently plump]], so we can infer that she has a steady food supply. Annagramma, growing up in poverty, always wanted but never had that for herself and her family; they barely ever even had enough.
* In Annagramma's view, respect is earned by power. Her talent lies in being a master magician who can perform incredible feats of power, but from the beginning of the end of ''Literature/AHatFullOfSky'' to the near entirety of ''Literature/{{Wintersmith}}'', she earns zero respect and even less love. Meanwhile, Petulia's talent lies in pigs, but she doesn't just earn respect in the same timeframe Annagramma loses it; people genuinely adore her. Annagramma can’t deduce what ''causes'' this disparity (hint: not treating people like they're deaf may ''really'' help her case, Annie).
Think about what these look like to her. In her eyes, Petulia gets everything she ever wanted and worked for without trying. She didn't ''need'' that Boffo kit to become green.
