Cryocoffin, the only way to travel the universe and never see it. Not until you wake up in the distant future and know nothing about where you are, where you came from and why there are nobody in the ship that has been sailing the sea made from stars forever. That is exactly what happened to Craft, who is the man in the coffin, except he wasn't in the discovery. Instead he had been doing that in his own personal fighter craft that looked too advanced for anything we've seen in the ST history.
What is really interesting is that the Computer at the heart of the Discovery has somehow managed to keep the ship functioning for God know how long. There are still no androids, no robots, no mechanoids helping the Ai. Maybe that is the reason why Sarah, the Ai, couldn't repair Craft's 'escape pod.' Her systems are automated, but in the order to function, she need arms and legs.
Sarah claims that she has been evolving herself while the crew has been gone for 'almost thousand years.' You almost wish that the StarFleet would have installed the Emergency Holograph System in the ship, before it disappeared. The problem however is that while Sarah entertains Craft in many ways, she never really explains how the crew left the ship and never came back.
When Craft explains to her how it is in his planet, and short after while asks her to join him for a dance in the bridge, the short starts to resemble a weird short Robisson Crusoe. I'm not sure, which one of them is Robinson and which is Friday, but it is sad that at the end, the Ai is doomed to drift for another thousand years alone.
Why they abandoned Discovery?
As a note CBS is doing a fantastic job with these mini episodes. They are much better than anything that other series has done in the youtube. But unlike with the youtube, they aren't as popular, because they don't reach as massive audience.
