Smallville: Season 6

Season Six revolves around Clark's discovery of who he is through two major storylines: 1) the tormented relationship between he and Lana Lang, as well as Lana's potentially strong affections for Lex, and 2) Lex Luthor's rapid loss of morality and Clark's realization that he alone can stop him. There is a third major storyline as well, dealing with a number of alien ghosts which escape from the Phantom Zone in the season premiere; Clark must round them up before they wreak too much havoc. There are a number of subplots too. The largest and most popular involves Oliver Queen, played by Justin Hartley, who was cast in the title role of "Smallville"'s failed spinoff "Aquaman." Queen is a young, attractive businessman who arrives in Metropolis with a dark secret: he is the Green Arrow (one of DC's most popular heroes), a hooded rogue who protects those who need protection. He is also a sort of Robin Hood - which is bad news for Clark, whose mother is now a full-fledged, popular politician. Queen also has a checkered past with Lex Luthor, which makes for one of the season's more interesting subplots. Others include Chloe's relationship with spunky young photographer Jimmy Olsen and Lois Lane's beginnings in journalism.
