This wasn't the sort of visit Kurumi had intended on having with Professor Williamson, but given the circumstances and that fact that Walnut had already peed on two first years in the common room for sitting on his chair...there really was no other way around it.
So, with
Walnut tucked under her arm, Kurumi approached the hut and knocked on the door twice as was customary to the Gryffindor. Please let Professor Williamson know what to do....
She also hoped that she would still be able to discuss her future in magical creatures...but Walnut's issues came first. Bleh.
