Eventually they get to the Charms classroom.
The desks are two per. Karen sits with Miranda. They get out their Charms books.
"...didn't you just eat breakfast?"
"Yep! But I left myself a present here! Good on me!" she says, and pats her own head. Sadde snorts.
At this moment Professor Flitwick calls class to order, looks approvingly at the one table where a Ravenclaw and Slytherin are sitting together, and announces that they are going to begin with Wingardium leviosa. He rephrases the instructions as found in the book, demonstrating correct grip ("most spells by volume are cast from this grip") and wand movement and incantation. Everyone has a feather to levitate.
Willow, on the other hand, looks quite frustrated by her lack of results, and frowns at her feather as she tries again.
Karen gets hers aloft - temporarily - on the first try. Miranda needs to try twice to get a waft, but her third incanting has the feather levitating very cooperatively.
Willow, on the other hand, continues failing, and is increasingly frustrated by this fact.
There does not seem to be anything she's doing wrong consistently, but each time she tries it she does something wrong. The main meta-problem appears to be that the more frustrated she gets with her failures, the more mistakes she makes.
She tries doing it slower, and this time she gets the wand movement wrong—too violent and forceful.
She tries that, too, but now her pronunciation is wrong, and she stifles a frustrated shriek at her feather after it fails to lift.
"I know!" she snaps, then closes her eyes and starts breathing deeply. She opens them and focuses on the feather, swish-and-flick perfectly, "Wingardium Leviosa!" perfectly...
And yet, it continues to not float.
"Looky here you little stupid feather, you either float or I'm setting you on fire!"
"I can probably fail at something around it, there's at least a decent chance it'll catch fire," says Sadde.
"Wingardium Leviosa!" she says at the feather and it... twitches. Very slightly, it raises about a third of an inch from the desk, but she just beams and says, "I did it! I did it! I'm a witch! I'm a real witch!"
She doesn't manage much more than that for the rest of the class, but her one little success has given her enough hope for the future!
Sadde learns how to hold a feather steady and even move it around a little without needing to meditate on it for ten minutes, and then tries doing the same with her pen, with mostly failures. Speaking of, she decides to write some notes on her little notepad about what works and what doesn't, before putting her stuff away.
Miranda and Karen wind up having their feathers chasing each other around in the air by the time Flitwick dismisses them.
"What do you eagles have up next?" she asks.
