After three seasons, everybody made it to Alpha Centauri! But the Lost in Space season 3 reveals that even when you get home, there are many problems. The final moments of Lost in Space season 3 resolved some things and changed some assumptions about the aliens that you might have had up until this point.
Here is how Lost in Space ended. It means something.
Hastings has a key that unlocks the defensive shield
The Robinsons are finally at Alpha Centauri. But they know that SAR and the hostile alien robots will come soon. They need something to knock out the attacking robot ships. What they need is an EMP shield, but in order to get one, they have to get a verbal command from Hastings (Douglas Hodge). Don’t remember who this guy is or why he is in jail? Back in season 2, Hastings tried to take over the Resolute using command codes that were given to him by Maureen Robinson. Why would she do that? Well, even though he was offscreen in season 1, Hastings basically blackmailed Maureen into getting those codes. He got Will into the 24th Colonist group, but only if she gave him the codes.
In season 3, Hastings is involved in something bad. But like Adler before him (who died in season 2), he ends up dead. This means that, for the most part, all of the human enemies of the Robinson family are dead by the end of season 3.
Half of the robots turn out to be good
Without any doubt, the biggest twist of Season 3 is that Will Robinson’s robot and Scarecrow from season 2 are not just flukes. The idea that people and robots can have special bonds is not actually that special. The idea of the robots changing their minds and defending humans is a twist in Lost in Space. Penny decides to show one attacking robot mercy, which changes its mind about who its enemy is. It gets named “Sally” for this. Several kids are able to do the process to make robots that fight for humans. There are also other robots who don’t like humans, so they fight too. This twist might not be good, but it usually works. This twist might seem a little corny, but the truth is it usually works. For the entire series, Lost in Space has shown that what made Will different was that he trusted the robot because he was different. Everyone else (except maybe Adler) trusted him too and followed him.
Lost in Space said that to solve the robot war is simply to say, “all you need is love.” Yes, it worked.
The robot put his Katra in Will’s heart
Okay. Okay. We know that the “katra” is a Vulcan idea of a soul. Right? And that’s from Star Trek? Well, it really feels like that happened in Lost in Space when the original robot saved Will by jumping-starting his heart with lightning. It seems like he was destroyed and turned to ash after he did this. But because Will had a mechanical heart, the robot downloaded his entire consciousness. This is why when SAR stabs him in the heart (for a second time this season), it backfired. The good robot’s programming took over SAR and used SAR’s body to become a new version of itself.
It is hard to understand the robot changing bodies in Lost in Space. It is not clear how the robot was able to take over SAR’s personality.
Dr. Smith’s fate
Oddly, one of the saddest moments in the ending of Lost in Space season 3 is when Dr. Smith decides she won’t kill Commander Radic. This man had proof that Jessica Harris was not Dr. Smith and might have been arrested before the robot attack. But then the original robot saved him, and they did not kill him.
Lost in Space ends with a family get-together that does not include Dr. Smith. In the end, she is put in jail, and Maureen visits her towards the end of the finale to give her contact info for when she gets out. In other words, Lost in Space has a happy ending, and its worst anti-hero, Dr. Smith, doesn’t die. She also does not get off scot-free, but it is easy to imagine a future where she gets out of jail and starts making trouble on Alpha Centauri once again.
