Did You Know?


At about 20 mins 30 secs: Finn repeatedly asks the grounders who is in charge here. The leader of the grounders raises a calming hand to his people and tells them to "Stay Calm" in his native tongue, Grounder Creole (per the subtitles).

The words he speaks sounds nearly identical to the English slang phrase "Chill out." See more »


The entire concept of radiation and its effects on the human body is incorrect. When Maya is burned and blistered by the "radiation contamination," her skin is blistered and burned in a very short period of time; this is typically only caused by thermal radiation, or direct contact with beta fallout from a nuclear blast, both occurring very shortly after the blast, not many years later. With radiation intense enough to burn her skin like that no human would be able to survive. The doctors say that the bodies of people from space have grown immune to the effects of radiation by filtering the radiation out of the bloodstream. The type of radiation that would cause burns like the burns on Maya is called ionizing radiation and passes directly through the body disrupting and destroying cells. It has nothing to do with circulating throughout the bloodstream. See more »
