"Bella, why don't you take Sherlock back to your room - I'm sure you know the way, Sherlock, but two days without sleep is no small thing for an eleven-year-old and the potion only helps so much - and I'll make excuses for the teachers."
Healer Song has actually been avoiding gendering Sherlock throughout this entire conversation. Perhaps this has something to do with the appointment Sherlock has with him at the end of the week.
"Sure," says Bella.
"I thought I'd upset you or something and you were being unfriendly," confesses Bella as they leave the infirmary.
"...oh," he says. "I'm sorry. No. I was just..." he shrugs, gestures helplessly, falls silent.
"Well, now I know better," says Bella. "How come you didn't tell me, though, I would've at least told you when I was going to be in the library even if I didn't have the idea of going to the healer..."
Bella purses her lips and allows the rest of the journey to their room to pass in silence. She collects the books she'll need for her remaining classes so she doesn't have to stop in after brooms, and says, "Euterpe won't count, will she?"
"Do you want me to close the window so she can't come in?" asks Bella uncertainly.
"...I... I think so," he says, looking down at the floor. "I'm sorry."
Bella shuts the window and ruffles his hair. "I will be completely not here until just a little before ten at night," she tells him. "Cross my heart. You get sleep, okay?"
And then potions.
"Sherlock hasn't been sleeping," Bella tells her as they sit down. "He can't sleep with somebody in the room. He's catching up now and the healer is going to give him a potion tomorrow night to see if that works."
"Yeah. If the potion doesn't work the healer might find a way to give him a single, or I'll just spend every afternoon in the library like I was probably going to do anyway and he'll have to sleep then even though it's not really enough time."
Tony makes a face. "Sucks to be him. Give him a hug for me, would you? You'll see him before I do."
"Sure, when I go back tonight," says Bella, setting up her cauldron for the day's potion. They are making a water purifying elixir.
"Sorry," says Bella. This potion, they don't get to keep; it's all graded, then collected for a representative from the ACAAM Charitable Crusaders to pick up and ship to somewhere in the Third World where sixth-grader water purification potions are apparently in high demand.
Bella raises her hand to ask if they should make more, for the Third Worlders who need it, and is told that this is a class, not a meeting of the ACAAMCC.
The representative from that organization hands her some promotional material on his way out.
And Bella's off to Social Studies, and then she hangs out in the library doing her homework until dinnertime, and then she goes to the cafeteria.
