"It's not gonna talk," he says, holding it out to her. "You can just shove it in your pocket for now, I guess, but try not to let it fall out. Okay, ready?"
Bella reaches out and touches the droplet. "Yeah - like so?"
The device glimmers. A glimmer passes over Bella, too, but it doesn't stick around; this has to be a stealthy spell, after all, if she's going to use it all the time.
Brilliance passes her the droplet and takes his hand away.
Then she stares at her arm.
Then she grins and breaks into a heedless run, and leaps into the air, and spins, and generally capers around like a baby goat crossed with a droplet of water on a hot griddle.
Bella's laughing too, breathless with it, breaking into random dance.
She lets him catch her, and she hugs him tight. "Thank you!"
"You're welcome! I'm glad you like it! Ooh, hugs. Hugs are awesome."
"Hugs're pretty awesome," Bella agrees. "It's great, it's the best thing, I feel amazing."
Grateful happy hugs! "It's amazing, I love it, it's like I'm telekinetic only with myself, I'll never trip over random nonexistent things again, I love it."
"Awwwwww." Squish! "I think hugs might be better than ice cream," he adds contemplatively.
Hugs hugs hugs. Even hugs are pleasanter with all this detailed obedient feedback from all her parts.
"I should try more flavours," he says, snuggling her some more. "I want to try everything."
"I'm getting that," she laughs. "You are one serious hedonist."
"I definitely am," he giggles. Hug hug hug. "I don't understand how anybody else isn't."
"Well, I'm also a lot more used to food and hugs than you are, maybe the novelty will wear off in seventeen years."
