Diamonds in the Sky
Directed by Neil Marshall
Don and "Dr. Smith" crash-land and must escape their Jupiter before the cockpit breaks off and falls into a gorge. Don's mechanical knowledge helps them in this endeavor. They discover Tam dead. Smith invokes Don's conscience twice: first when he rescues Debbie the Chicken, and second when he rescues Angela, another survivor who is severely injured and unconscious.
Meanwhile, the Robinsons have gained access to their ship thanks to the Robot's help, who also helps them dry out the interior. They begin the work of repairing it and extracting it from the ice, while John, Maureen, Will, and the Robot mount an expedition to another crash site to look for survivors. Judy is experiencing traumatic flashbacks to her experience beneath the ice and thus much of the burden falls to Penny. She observes an oncoming, dangerous storm and resolves to rescue them using the ship's Chariot, an all-terrain vehicle.
Maureen and John argue over who's in charge. Maureen asks Will to have the Robot lead them to its crashed ship. There, while playing catch with Will, the Robot accidentally reactivates the ship and its holographic star map. It also experiences flashes of its lost memory, which Will also sees: of it attacking the Resolute. Horrified, he runs away, but is persuaded that the Robot is not evil when it displays its willingness to walk off a cliff at his command. As they start walking back to their own ship, the storm begins, but Penny shows up to rescue them.
Don and Smith, with the unconscious Angela, also see the storm coming and take refuge beneath an overhang. Smith, who's been deceiving Don about her past, offers to go get help, leaving him with their last flare. As the family desperately races the storm, Will spots the flare in the distance and they change course to pick up the survivor... Smith, who lied and fled to save herself, leaving Don stranded. They make it back to their Jupiter barely in time as the storm closes in. Smith sees the Robot in Will's care and recognizes it for what it truly is.
