Has Lex Luther offically crossed over to the dark side in smallville season 6?

In the season 6 Episode "Subterranean." At the end of the episode Lex was walking from Area 33.1 and all of the metor freaks were reaching their hands out of jail cells. And the song Prelude 12/21 by AFI was playing. Is this a sign now that Lex is totally evil and that in this season 6 Clark will become Superman? Does anyone have a strong feeling it's this season?
