Kirk enters the bridge as the crew performs their preparations. Uhura announces that Lieutenant Ilia, the navigator, has arrived. And she's Deltan, whatever that means.
Based on Ilia's appearance, the Deltan are a species of bald, beautiful ladies.
Ilia and Decker seem to know each other. Their longing looks make us think that they knew each other verywell.
Uhura has another message: the final six crew members are about to arrive. The only problem is that one of them doesn't want to get on the transporter.
Kirk heads to the transporter room. He watches as a bearded man in the most 70s outfit ever appears. This is Leonard "Bones" McCoy, the medical officer from the original series and Kirk's bro for life.
Bones didn't want to come back on the ship, but was basically conscripted into service, most likely at the behest of Kirk.
The lights are shutting off in the Enterprise's space dock as the crew performs their final checks. With that, the ship powers on.
The Enterprise lumbers forward. Kirk gives the order to travel at half of "warp" speed, which is Star Trek's brand of faster-than-light travel.
