Josie Flint didn't normally send owls like that. She'd send silly ones, but never ones like this. Theta could take an early lunch, check on her. If it was just a case of mixing two potions and sleeping days that was easily fixed. If she was poorly she could bring her to a healer. Theta seized her coat and scribbled a note back with Josie's owl.
Josie,
I'm on my way! Don't panic.
Theta xx
