The way Bella can suddenly do gymnastics after she and Soph have been moved in for a couple of weeks is weirdest.
Scratch that: the apparition that shows up in their bedroom, causing Bella to punch the bunk above her with surprising force in order to wake Soph and confirm that she's not hallucinating? That's weirdest. And so is what it has to say.
Soph sleepily wonders if Slayers have time to play softball. Bella opines that she does not think any of this is a good reason for her to start playing softball.
Soph goes to sleep. Bella stays up, at first, then she crashes too.
And the next day during her free period she's in the library, peering through the vampire books.
"Would you say," says Bella distantly, eyes still shut, "that it has a texture - the power we're looking for?"
"Sort of like - standing under a waterfall. That springs into existence on top of my head." She opens one eye, then the other.
"Why is it that people don't find these things when they're just zoning out in English or something?" wonders Soph.
"...Okay, Bella asked about a texture but what about a temperature?"
"Definitely," she says. "For me it's a little warm, and it's like a feeling. When do you feel most like yourself?"
"Great. However you feel first thing in the morning, try to feel that, then follow that feeling, okay?"
"Okay..." Soph flops over onto the arm of the couch, possibly for effect, squirms till she's comfy, and then, a minute later, puts a hand on her sternum. "...Maybe I have it."
"Damn straight," Delilah says, and leans forward to take Soph's free hand. She turns it palm up and taps the palm with one finger. "Now put it here. Just a little."
"You'll make a little ball of light, or maybe sparkles or something, I don't fucking know. Neville's here, which means nobody'll get hurt, because he's a special snowflake magical lightning rod anomaly Mary Sue, okay? Just try it."
"Gary Stu," Neville grumbles, but he also relaxes. "You can go ahead and try too, Bella, if you want."
Bella glances between the Longbottom siblings, then puts her hand out, palm up, and makes a concentrating sort of face.
Soph gets the trick first, though she has to mime actually plucking some magic from her breastbone like a tuft of cotton candy: she gets a little spring-green cloud that looks like it's full of lightning.
She admires it!
