Sheik was not a stranger to her impromptu music sessions attracting other students, and was therefore rather apathetic to the Pokemon all up ins her personal space. It was perhaps lucky that she was not terribly possessive of the harp, and she offered it towards Casey in the event she wanted to give it an experimental strum (it certainly looked that way).

Telpathy, of course, was not unfamiliar either, though she'd obviously have to respond in a more verbal manner.

"Hello. Are you a new student?"
