"Alien: Earth" season 1 has come to an end, and it sticks the landing on practically every level. It all points to an exciting season 2, but there is one thing about the season 1 finale that I just can't square with the rest of it. And sadly, yes, I'm complaining once again about the worst character on "Alien: Earth," Boy Kavalier. The answer we finally get in the season finale isn't just disappointing, it flies in the face of the very rules the show has established around its cyberpunk world. Boy Kavalier built Prodigy by ... being born with a big brain and having a can-do attitude.
