The second thing she noticed was that he was changing, so she quickly looked away to grant him some kind of privacy.
He seemed as surprised as she was as first, but quickly seemed to regain his composer and spoke to her.

'But... this is room 9.., right?' she looked at the map dumbfounded and annoyed, before noticing she had misread the piece of paper. A slight blush appeared on her face and her eyes widened in surprise at her own mistake. She bowed deeply, hands crossed at her knees and her eyes shut tightly. 'My deepest apologies sir Aiden! It seems I have misread the map.' she exclaimed. 'I shall take my leave.'
