The experience of seeing through khan's eyes were a bit disorienting, Alex couldn't exert control on the spirit, so he could only go along for the ride as Khan completed the mission that Alex had given to him. As opposed to the first time Khan had hatched and the ensuing days after, the Kamaitachi had grown in maturity quite a bit, of course he was still a bit playful, but now he could actually focus on his tasks and get things done. It was completely by accident Alex had discovered that he and Khan could share each other's senses. He could see, hear, smell and sometimes even taste the things Khan could, and vice versa.
