Leonardo had settled in quite nicely over the last couple of days. His head had been mostly buried in books, trying to gather a general understanding of the things that had happened. He was fascinated by the tv and the computer, architecture, art, video games, simple things like tap water; everything needed to be examined. Plus, he had gotten so indredibly fortunate to be with such fascinating, talented people who treated him with great patience.
When he heard the knock at the door, Leonardo was sketching his room, trying to make it feel more real to him, and simultaneously grasp the design decisions of this new age. He raised to his feet and opened the door wide, then bowed and smiled brightly as he spotted his unusual-looking friend.
"Always, mio amico, always, after everything you've done for me. It's so nice to see you again! How can I be of service?"
