There's more to this strip than meets the eye.The first thing that strikes me as odd is that the recipient of the award in Sandra's dream is MRS. North. You'd think that this is Sandra dreaming of herself when she gets older, but why would she be called MRS. North? This is because it's not just a dream to serve as the punchline to a joke. That was actually one of Sandra's memories of her mother before the latter passed away, hence why she wanted to make a name for herself in the field of math, and why the mere act of her not remembering a formula is depressing her so much (look at her face, it's not just disappointed, it's on the verge of tears.)
This is not Cloud using profanity.Instead, he's so frustrated that he can't form words at the moment, and is just grunting and screaming.
Sandra and Woo and Calvin and Hobbes exist in the same universe.Remember the "little raccoon" storyline which was one of the most tear-jerking moments in Calvin and Hobbes? Well, the raccoon didn't die. Instead, he crawled away after seeing what Calvin was capable of. Or maybe he was just afraid that Hobbes would have him for a snack. Calvin's dad, who couldn't quite admit this to him, made up the story of his death. (Note that we never actually see the raccoon, either alive or dead, in Watterson's artwork.) In the meantime, the raccoon was found by Mr. Farley, who caged him and generally treated him badly, until he grew old and wise enough to pick the lock of his cage, and escape into the city. Sandra found him (strip 1), took him home (strip 2), and that's where Sandra and Woo began. The trouble with this one is that it's not that wild.
The raccoon goddess is attempting selective breeding.That's why she was suggesting Butterfly settle down and have kids; the goddess wants Butterfly's superior-climbing genes passed on to the next generation. Which means eventually we'll see the goddess nudge a raccoon she deems "inferior" into harm's way.
Larisa is Natalia Vasylchenko on a deep cover missionSince the new enemy, a similarly immortal (resp. unaging) ruler of an ancient civilization appeared to be based in the US, Natalia and two Russian (or Ukrainian Russian-speaking) Zvezda operatives posing as her parents (since her parents were revealed to be in cahoots with the "Smokers" organization behind Governor Kyoushirou Jimon) were sent on a deep-cover mission to the US to find and gather intelligence on the enemy. Natalia could easily pose as an Russian, since she and her parents were part of the Russian-speaking population of Ukraine and Russian is basically her mother tongue.
The real reason Landon's mum wanted Larissa to be burned at a stakeSince her screaming loudly into the telephone handset, the Catholic church official she phoned misunderstood her for wanting Larissa being burned as a witch. In reality, she wanted her to be burned because of heresy, since she thinks, that Larissa, as a Russian, is a member of the Russian Orthodox Church.
