Shizune went to sign her name, but stopped when the PDA was handed over. She tried to avoid having to resort to this sort of thing... but it would cause to much trouble to turn it down now, not to mention this woman didn't look very patient.

I'm Shizune Hakamichi. I just arrived here by train and it seems I'm supposed to be assigned to a school or something. I don't suppose you can tell me what's going on?

Given that she didn't hear any of what Santana asked her, she just ended up retyping what she'd signed before handing the PDA back.
