Jim and I were friends until the end after that. We stuck together and protected each other through school, I-Chaya's death, and even through our admission to Starfleet.
Even when Jim became captain of the Enterprise we stayed close, for he had assigned me to be his Science Officer. Even Leonard, now Dr. McCoy, was with us on our ship. Together with our crew, including Lieutenant Uhura, we had many, many amazing adventures.
