There was sound near him. For a moment, Azelf stayed still. His eyes narrowed at the coming presence. They might have thought they were hiding, but it was very hard to sneak up on someone who's senses were inhuman. It was not who he was waiting for, so he had no intrest in being seen at the moment. A puff of black smoke curled around him, as with a slight crack he vanished from his location upon the poolside. His first instinct was to go up. Unfortunately, the area seemed to be preocupied as well. He appeared behind the doctor, and who seemed to be a new playmate of his. Neither seemed to notice him right away which was good. He stood there silently for a second, the girl he recognized.
It was the one from outside, this was quite interesting indeed. His skills with blending in and stealth came in handy now, as he moved more to the girls blindspot so she would not see him. This was either an attempt at romance, or a very good manipulation plot. Azelf knew better, most likely it was leaning more towards the second one. He was not worried of her seeing him, if she turned, he could easily teleport out before she saw even a hair of him. Right now though, he found the sight rather ammusing to be honest. It was not every day, one got to spy upon a doctor attempting to "woo" one of the patients. His tail swayed behind him lightly, as he sat down upon a couch behind the girl's field of view. He crossed his legs casually, as he rested his head upon his left hand. He smiled, slightly catching the doctor's eye.
