The episode opens with Will Robinson (Billy Mumy) and Doctor Smith (Jonathan Harris) sleeping outside the Jupiter 2 in the hopes that their elaborate alarm system would entrap a mysterious invader who lurked somewhere in the shadows. This is one of those weird character inconsistencies when it comes to the cowardly Doctor Smith as we get no reason as to why he’d agree to rough it outside their perfectly safe spaceship when there is a possibly dangerous intruder about, but even stranger is that the Jupiter 2 had already been established as having force fields so such an alarm systems doesn’t seem to be all that needed in the first place. Regardless of its necessity it does alert Will, who has to kick Doctor Smith to wake up, that there is in fact an intruder about.
“Danger Will Robinson its Kurt Russell.”After this “menacing” intruder tosses as spear at Will and Doctor Smith, which of course misses wildly, he is introduced as Quano (Kurt Russell) and soon the whole Robinson family has to deal with this rather obnoxious visitor. “I am called Quano, I am twelve years old, I am very brave and strong, would you like to fight and see who is the better man?” This challenge was addressed to Will and is basicly crux to this episode's plot; Quano is from an alien world ruled by a warrior class with strength and courage being weighed above all else, and at a certain age a young warrior must seek out an opponent to prove he is the best. I’m not sure what kind of warrior race would consider beating up little Billy Mumy as worthy proof of badassery but who am I to judge alien cultures.
Note: At the time of shooting of this episode Billy Mummy had just turned twelve and Kurt Russell was actually turning fifteen in a couple of weeks. So yeah, totally fair fight.
It’s also made clear that Quano is from a rather sexist planet as when Penny Robinson (Angela Cartwright) questions him he responds, “I do not speak to weak and worthless girls.” This series is a major product of the 60s so the battle of the sexes was bound to make an appearance it’s just unfortunate that the script doesn’t have the women doing anything other than poor coffee, make breakfast and worrying about the menfolk. Wouldn’t it have been cool if Penny was the one to end up defeating Quano?
