The Empath: November is extraordinarily sensitive. Against her, this means that she gets hurt by things such as having leaves fall on her face. More impressively, she can sense death, tell when people have noble blood — or even if they've only married into royalty! — and is usually able to surmise the intentions of the people she brings into the group(she senses Perrault's boredom, as well as Clare's innocence). This is a Call Back to her source story, The Princess and the Pea, where it is the Princess's sensitivity that is used to determine her royal lineage.
Forbidden Fruit: Red picks the Beast's roses and puts one behind November's ear. The Beast is furious. Of course it doesn't help that first they smashed down his gate, broke into his house and wandered around taking random objects from it.
"Aha, I can see where this is going. Mysterious old beggar women need to be handled very, very carefully."
Invoked intentionally by Perrault when tricking an inn keeper to let them stay the night for free. He convinced the man that they were fairies, figuring he probably knew his fairytales well enough that he wouldn't question strange forms of payment (like a dead bird) if they came from the Fair folk.
Perrault: Now, if you were to bury this bird behind your inn...should you then find, say, a golden tree with diamond fruit growing upon that very spot three days later...well, that would be quite something, wouldn't it?
Get Out: Red to November, during the fight with the witch. It's for her protection.
Guile Hero: Perrault, very much. Well, maybe Guile Anti-Hero.
It Amused Me: Perrault's appropriately cat-like motivation. He had as plush a lifestyle as he could hope for after turning a bumpkin into a marquis by guile and complains about the dangers in November's quest, but when presented with an opportunity to escape easily... "No, not yet."
Loners Are Freaks: Red has lived by herself in the middle of the forest for several years and is seen as a witch by the locals who see her. Admittedly, she didn't seem to go out of her way to correct this idea.
Meaningful Rename: When November asks Red to give her her name, Red pretends to believe it's asking for this.
Merciful Minion: Claire's mother-in-law, receiving a letter to execute Claire, had her flee for her life. Oops. Turns out the letter was tampered with; her husband had actually ordered her treated well and is now heartbroken.
Sand in My Eyes: The Beast claims he got dust in his eye when he starts talking about Beauty.
Satan: The devil appears in Clare's backstory convincing her parents to sell her to him and promises the soldier riches if he does not shave, bathe, or pray for seven years. Seems to be of the deception and bargaining version. Seems to work in opposition to and may be connected to the disappearance of the Moon, who stops him from taking Clare in her backstory.
The Scapegoat: The villagers are eager to blame Clare for the disappearance of their children, rather than admit to their complicity in letting them wander too far into the woods.
Schedule Slip: Following the October 2009 hurricane in the Philippines (the author's home country), the webcomic went for over a year without updating. Other long breaks have occurred, but the author has vowed never to abandon the story.
Self Fulfilling Prophecy: The Witch was driven from her village because the townspeople accused of being a witch after her husband abandoned her and her children. Living alone in the woods with a sick and dying son and unable to feed both children turned her into somethingmuchworse.
Stick Em Up: Clare tried this, but her prey had nothing to give.
Stranger in a Familiar Land: Klaus and Anna finally get rescued from the witch and taken back to their weepy father... but they still remember how he sent them off to die alone in the woods. Clare points out that when something horrible happens, it's never really home again.
The Strategist: Perrault. November seeks him out because of this reputation.
Was It Really Worth It?: November charges into a forest to find two recently-vanished children and clear the name of the woman the villagers plan to burn, thinking she is a witch who has abducted and killed their children. As it turns out, there is a real witch in the forest who has indeed killed many children. Thing is, the two who went missing most recently were abandoned there by their father, because life is so hard in the village that the villagers can barely feed themselves. Not all parents can find the balls to abandon children they can't feed there- instead, they simply take no measures to stop them from doing so. November and the others take the rescued kids home, have the scapegoat freed and tell everyone that the witch is dead. Problem is, life isn't going to get any easier for the village, the rescued kids will forever remember how their father abandoned them to die, and thus will probably leave to find a new home. November ends up wondering if she really helped anyone.
When All You Have Is a Hammer: When November, Red, and Perrault reach the Beast's estate's gate, Perrault, having gotten on the other side by himself, lays out a detailed plan of tricking the then-unknown-owners of the mansion into vacating the place and letting the other two in. Red just smashes the gate in.
Wicked Witch: Attributed to both Red and Clare. It's not true for either.
Word of God: The author provides footnotes for those who do not catch the allusions.
