Hyperion smiled politely at the vaguely familiar man, while internally racking his brains to try and work out who he was. He was dressed in perfectly acceptable Muggle clothing, but there was something about him that seemed out of place. After a few seconds, a hazy recollection of the man hurrying through the Atrium in a full set of Wizard's robes surfaced, and Hyperion's grinned widened. "No really, I'm very sorry," he said with a short bow. "I don't tend to be so utterly unobservant."
He quirked an eyebrow, a smirking grin still evident on his face. "Maybe we both should have been paying more attention then," he queried, taking a moment to take the man in and finding him to be quite attractive. "I know what it's like when you're on the hunt for a good book," he added, reaching up and taking down two copies of the book, and offering one to the man. "Plus Muggle stories are always better I find," he added casually, aware that the word 'Muggle' would only earn him a confused look if he was wrong about the man's identity.
