"I hadn't noticed," he lies transparently, scrubbing at his cheek with the corresponding wrist. It does nothing to erase the blush.
"...I could probably figure it out if I put my mind to it but I really don't want to because you're standing right there paying attention to me and my blushing," he mutters.
"I guess I could just leave and suffer through an itchy mystery till I see you at school again."
"Sorry, I'm being pushy," laughs Beila. "I'm a pushy Avatar. I'll leave you be." She flicks her glider open.
"No problem." She takes a running start, bends wind under the glider wings, and flies away.

Beila attends school at the start of the next school week. She is practicing maintaining ice; she has a bit of it in her water bottle and she's refreezing it whenever it tries to melt.
