Can't be worse than teaching the shounen tantei. Conan's already picked up on the need to mask his enthusiasm, evidenced by the way he only nods in response to his counterpart's announcement.

He finds himself a quiet hiding place in the shadows, letting his counterpart get ahead of him as he pulls himself into a seated position. Its not strictly necessary; Shinichi's been doing this particular meditative exercise for years. But Conan's body isn't accustomed to it, and taking up the sitting position helps him focus -- and focus he does. It doesn't take long to slip into the right pattern; breathing carefully controlled, senses hyper-aware, at one with the surrounding corridors. Preparation done, Conan takes up the challenge again.
