Luckily, that\u2019s not the case this time. \u201cFrom the beginning, we\u2019ve always viewed this particular story of the Robinsons as a trilogy,\u201d showrunner Zack Estrin said last year. \u201cA three-part epic family adventure with a clear beginning, middle and end.\u201d<\/p>\n
Whether it really was always the case that Lost in Space would climax with its third season, there\u2019s little to suggest that its makers have had to rush to tie things up. It\u2019s been a largely successful season and its final episode, \u2018Trust\u2019, packs a decent emotional punch. Sure, a few characters feel desperately underserved, but that\u2019s a problem inherent for a show with a cast as overspilling as this one.<\/p>
The episode kicks off with Alpha Centauri already under attack from the robots, while Smith is stalking the hospital with the aim of murdering her old nemesis, Captain Radic, who\u2019s there in a medically-induced coma. That\u2019s the plan, anyway, until Robot interrupts her with a \u201cHelp, Dr Smith\u201d. \u201cHelp who?\u201d she asks, but it becomes clear Robot means her as he reaches out to take the syringe from her.<\/p>\n
Meanwhile, Will, Penny and Judy have been sent away to the planet\u2019s copper mine, for safety, supposedly. But the convoy of chariots is stopped when an army of robots land in front of them. It\u2019s then that Will figures out what the invaders are after \u2013 it\u2019s the engine from SAR\u2019s ship, which the robots plan to use as a bomb.<\/p>\n
An incapacitated Will (he\u2019s still recovering from his heart transplant) tells Penny she must keep the engine away from the robots. \u201cIt\u2019s got to be you,\u201d he tells his sister. \u201cYou\u2019re smart, brave, and you\u2019re stronger than you think.\u201d<\/p>\n

Will travels on the Jupiter 2 with Dr Smith, but his new artificial heart begins to fail him. Robot saves Will, apparently destroying itself in the process. Later, Dr Smith confides in Will that the Robot saved her when she was about \u201cto do something you can\u2019t come back from\u201d.<\/p>\n
John and Maureen face the remaining robots, including SAR, but fail to kill him. At the last minute, the others arrive, including Will, whom SAR attempts to stab. \u201cHe knew you\u2019d go for my heart again,\u201d Robinson Jr says, and with that, Robot\u2019s data is transferred, killing SAR and reviving Robot in the process.<\/p>\n
The final moments of the episode show life after that dramatic showdown. Maureen and Don are spending most of their time, it seems, in orbit, constructing a new ship to replace the Resolute, while John is just chilling on Alpha Centauri (\u201cthey say soldiers, more than anyone else, appreciate the value of peace,\u201d Penny tells us in a voiceover). Judy is working in the medical facility now and Dr Smith is finally in custody after delivering a confession to a now-awake Radic. The episode\u2019s final scene takes place around the Robinsons\u2019 dinner table, with the family (plus Don) tucking in to a hearty meal while Will tells them of his plan to explore the galaxy, with Robot by his side.<\/p>\n
