Sasuke frowned, not seeing any disruption in his chakra flow. He refused to believe he wasn't caught in a Genjutsu, though, because nothing else would explain the old man in twinkling, swirling robes. It wasn't just the old man either. All around him were men an women of varying ages in robes of all sorts of atrocious colors. Some of them made even Naruto's old track suit look respectable, and he hadn't thought that was possible.
He kept his hands by his sides, allowing his fingers to brush one of hidden pockets. A small flick of his wrist and he would have a finger in a kunai ring.
Common sense allowed him to consider the possibility that his surroundings were real. He wouldn't want to risk standing in place and making these odd people think him brain dead. They may kill him if they though him unsuitable for their purposes. They'd summoned him from the war somehow without reversing the summoning jutsu, so they obviously had some unknown power. He'd had too many narrow victories to still rush into battle without any intel on his enemy's abilities.
He looked to the old man in the twinkling robes. The leader, if the people's positions around him were any indication. "Who are you?" No pointing asking where they were at the moment.
The leader smiled. A quick examination of his body language revealed that his grandfatherly expression was genuine, though slightly exaggerated. Either he saw that he was only fifteen years old and assumed that he was a defenseless child in need if comforting or realized that being forced into a strange new environment might be rather disorienting. Considering that he was the one who summoned HIM, and the chokuto hilt sticking out of his belt, it was most likely the latter. After all, unless it was an accidental summoning, he almost certainly knew that he was at least slightly competent.
"I am Headmaster Albus Dumbledore. I would like to welcome you to the Headquarters of the Order of the Phoenix."
